My most recent immigrant ancestors were some of my great-great grandparents.
I have other ancestors who were here before the Revolution.
My paternal grandparents were immigrants back around 1900 from the Köln area via Canada. My maternal antecedents have been mucking about North America since the early 1600s. One was a crewman on the Sea Venture.
My great-uncle got into genealogy after he retired, so he did most of the legwork with the Magills. Both of my grandmothers were Quakers. The Friends keep meticulous records. My maternal grandfather’s family stayed in the same area for a couple hundred years.
I’ll let it go… this time. 
For the horse thread, I selected that I ride often. When I ride it is because my gf wants company on her ride and I love her too much to decline. For her it is her passion.
I’ve ridden many a quarter horse, if you define that as “horse that is in front of KMart and costs a quarter.” I’ve never been on a flesh and blood creature.
My dad was adopted so I don’t know his background. My mother’s family is from Italy. Some of her maternal aunts and uncles were born in the Old Country but her own mother was born here in the States. Her father was born here.
My paternal grandparents were (they’ve passed decades ago) Eastern European immigrants, and a good thing for me, as most of that branch of the family did not try to leave Europe until it was too late. My father’s research has found almost no survivors after WW2.
My maternal grandparents were, to the best of my knowledge, the first generation born in the states, and we have more extended family on that side, but aren’t close.
We have emigrants in my parent’s generation, as my aunt (father’s sister), her husband, and three cousins emigrated to Israel when I was a young child, but that’s just an aside for this thread since it’s been brought up a few times.
The Friends would excommunicate you at the drop of a hat. (One of my ancestors was expelled for talking back to her husband. Three of my ancestors were expelled for joining the army in various wars.) When you repented, they would take you back. Both events would be recorded.
Birth, marriage, and death records were as haphazard as those of any other church. But the disciplinary records were numerous, detailed, and meticulous. 
My grandfather was an immigrant from Belgium.
We kept a lot of the different customs from that area for many years including celebrating St. Nick’s Day somewhat different than usual.
We had a fierce character called Zwarte Piet (Black Peter) who would pound on the windows and growl for what seemed forever before the door would open and a treat bag would be hurled into the kitchen. It was definitely frightful and I stopped this particular custom when my son was young once I saw how scared he was. I guess I had forgotten the childhood fear I experienced.
According to some friends I have in the Netherlands this custom still exists in some parts.
All of my friends in the Catholic grade school I attended told stories of calmly leaving a shoe out for St. Nick to fill. I was traumatized for years by the harrowing pre-treat experience.
My great-grandparents on my father’s father’s side were immigrants from what today would be the Czech Republic, at the time part of the Austrio-Hungarian Empire, circa 1910. I’m told my grandfather grew up speaking German at home and didn’t actually learn English until he started school.
AFIK the rest of my ancestors came to the US earlier than that, more like 1850s, so that would be further back than great-grandparents.
We did our blood types in high school biology class, but it was not EldonCard. We put our blood on two slides, one with a drop of anti-A serum, one with a drop of anti-B serum, and looked at the clots under a microscope.
You’re close to me. My maternal grandparents were immigrants (not at the same time), but none of my dad’s ancestors immigrated later than the 1830s. I’ve found some 17th C immigrant ancestors, and, if I cared (I don’t) I have multiple qualifications to be a member of the DAR.
Forgot about the horse question: When I was 3 or 4, there was little pony ride set-up in an empty lot at the corner of Overland Avenue and Pico Blvd. My aunt took me and my older sister. I’d never even seen a horse in person before that, so I was a bit frightened. The guy leading the ponies around (he was probably a college kid) asked me if I wanted go slow or fast. I said slow. My aunt just tore me up afterwards saying how I’d embarassed her. I hated horses for quite a while after that (poor things – not their fault), and I was never that stereotypical horse crazy tweenager.

My first presidential election was 1980. I was disappointed with Carter, but didn’t really like Reagan either. I ended up voting for Anderson. Looking back, I kind of regret that choice, but I was young.

My parents are both immigrants. They came to the US together (they had recently married) from Eastern Europe in the 1950s.
Same re: high-school blood typing. I was unable to bring myself to prick myself with a pin, but quite happy for one of the other kids to do it for me.
Re: horse, I voted “once and never again,” but only because I went once and it’s unlikely to come up in the future. I would happily go again, but I just can’t see making it happen.
Never even heard of Eldoncard.
Me, too. With another test for rhesus factor. But i decided that was “similar”. I actually got the wrong result from that blood test. It came out rh negative. But both my parents were positive, and every single child in my class was rh negative. So i guessed the reagent had gone bad. Later tests revealed that i am, in fact, positive.
Same.
My parents told me my blood type when I was a child. Not sure why, but I think they told my sister hers too.
All of my grandparents and some of my great-grandparents were born in Texas. Their families came from the eastern US.
I won’t answer calls on my cell from unfamiliar or blocked numbers, but just let them go to voicemail, if they want. We haven’t had a landline at home in about a decade or so, and don’t miss it at all.
I like answering phone, mail and online polls, for some reason, and strive to be truthful. If I can help Democratic candidates and issues by doing so, so much the better.
I’ve never voted for a third-party candidate for any office, I think. I’d be open to the prospect, if the Dem candidate was bad and the Republican was even worse, but it just hasn’t happened yet. I can’t imagine ever voting for a third-party candidate for POTUS or for Governor of Ohio, though, because the stakes are too high and he or she would likely just be a spoiler.
My earliest relative on my father’s side arrived on these fair shores in 1827, a potter from Staffordshire, England. The earliest on my mother’s side was in the late 1600s IIRC; I don’t remember his, her or their profession(s). Both of my grandfathers, and one of my two older sisters, are really into genealogy.
I rode horses now and then as a kid, but haven’t since, I think, the mid-Nineties. I don’t really miss it, but wouldn’t mind doing it again if I had the chance. A friend of mine is a Napoleonic Wars reenactor and has been in some big cavalry events - looks like fun!
Think I learned my blood type when I first donated in a Red Cross blood drive in my late teens, although it might have been when I had a blood test done for some reason as a kid.
Don’t know my blood type.
I’ve had horses for most of my life (and I’m 60+), and at one point they were my main source of income. I’ve had as many as 10 but I’m down to one horse an 4 goats for friends for him. I bred, raised trained him, he’s out of a QH mare I owned and by a TB sire. I can’t believe he’s 25 now.
I’m one of those horse crazy little girls who never outgrew it 
The horse poll didn’t quite fit me. I rode a horse several times when I was younger. I probably never will again.
I learned my blood type in the Army when they put it on my dog tags. A+ by the way.
My maternal grandmother was supposed to be born in America but her mother went back to Italy to visit her in-laws when she found out she was pregnant. Her doctor wouldn’t let her travel. My grandmother wound up being born in Italy and had to go through Ellis Island. My paternal grandfather was born long before Ellis Island was opened. My other two grandparents were first generation Americans.
