Does or did your father have a mustache?
Mine started one for the first time shortly after his 90th birthday.
Idle curiosity strikes. 
My dad had a mustache when I was a kid. He started the clean shave look in his late 30s. I can remember it being kind of jarring.
No, but his father did.
Mine didn’t, but I’ve had one pretty regularly since college.
My paternal grandfather is the only person in my extended family that has ever had facial hair. (in his case, just a mustache).
My other grandfather, as well as my father, brothers, uncle, and nephews are all (or were) clean shaven. Me too.
Not only no but hell no. Not even sideburns. Never saw him not shave every day.
My father had a full beard. I guess that technically included a moustache, given that he didn’t go for the Abe Lincoln approach, but you’d never call him “that guy with a moustache”.
My own lack of a beard stems mostly from not wanting to look like my father, as I consider shaving to be an annoying nuisance.
My Dad had one for a year or two in his early forties, after he stopped sporting a flat top. The weird thing is that it grew in reddish even though his hair was black. I don’t think Mom cared for it much.
Same here. My dad was in the World War 2 generation. No beard, no mustache, no sideburns, and get your hair cut at least twice a month or you are a d*** dirty hippy.
My Dad grew a mustache in the 70’s when he was sporting Leisure Suits with intensely patterned shirts. No doubt channeling Burt Reynolds (although Dad was better looking.) On a completely unrelated note he got a Burmese cat around the same time he grew the mustache.
Yeah, he has one. I think at times he shaves it off, but his hair is kinda light so it’s not that striking when it’s gone.
Me three.
I remember my dad (1920-98) telling me one time that in business he didn’t trust a man with facial hair! 
Pops grew a moustache and beard in his late thirties. Rocked that look the rest of his life.
My dad was in the generation that was drafted for WW 2. He never had a moustache. The only time I ever saw him unshaven was when he was very sick for several days. His hair was cut short, but not crew-cut short. I let my hair grow long in the late 1960s, and I grew a moustache to keep people from calling me “Miss.” I’ve had shorter hair since the early 70s, but I kept the cookie duster all these years.
I’ve never seen my dad’s upper lip. My mom hasn’t either and they’ve been married 40 years. He sported a beard until the mid-80’s and then went with just a moustache and never looked back. It doesn’t hurt that he grows a good moustache.
ETA: I never knew it had multiple spellings until this thread. It’s not something I spell often.
I come from a long line of hairy men, but neither my father nor grandfathers sported facial hair.
My dad, who’ll be 70 next month, had a thick, luxurious black mustache when we lived in Manhattan in the late Seventies. We call it his “disco mustache”. Dad was a real happenin’ dude.
My father was clean-shaven… then had a mustache… and finally had a beard.
At one point, he, my brother and I all had 'staches.
My Daddy never had facial hair. He was a blond, with a flat top hair cut. He had a really bad reaction to a penicillin shot and was in ICU for 3 days and in the hospital for 9 days. So his beard grew in. Surprisingly it was bright red. He shaved as soon as he was able.
