If memory serves, some time ago somebody on SDMB was handing out sainthoods and I was dubbed,
St. QuickSilver: A mercurial fellow.
Plagued with nagging curiousity and lack of better ways to spend my time, my search led me to this list of Actual Patron Saints.
My patron saint (of computers and the internet) is St. Isidore of Seville, with this bio.
I grew up reading Saints books. I wanted to be a saint or martyr when I was little.
As I grew up and took my own path, I never forgot one saint that always bothered me as a kid. I was too young to figure out the why’s of it all, but she set off my odd-person vibe even though she was in a book and long dead.
St. Rose of Lima, Peru If this woman lived today, she would be committed.
Here’s the original thread. It was Swimming Riddles.
I’m apparently the patron saint of blond teenage no-talents with breast implants.
And candy corn.
Apparently there’s a patron saint of Medical Technologists! Well, ok, it says technicians but I’m going to assume St. Albert is flexible.
One thing I wholeheartedly disagree with though, is a quote from lower on the page:
What is that about?
Here’s another site for patron saints.

Apparently there are several saints who look after us bakers, but the one who focuses most directly on it is St. Honorius of Amiens.
…damn you’re good.
Not surprisingly, my memory fails me. I’m simply the Patron Saint of Thermometers. Still, mercurial isn’t so far off. 
Individual thoughts and opinions are discouraged.
Hmm, counting myself as a librarian, I get St. Jerome
Hmm,
Bad temper, eh?
Moi?
Who the hell says I’ve got a bad temper? I’ll kick the bastard!
Oh come on now… surely more of you have a patron saint.
I know of a few who really need one!

St Joseph of Cupertino.
Patron saint of Aviators, and not-so-coincidentally, also my confirmation name.
My new namesake is just as good.
Maybe someone can help me out with the terminology.
Is a Patron Saint the saint with whom you most identify? Is it job specific? or related to your name or the day you were born? Can you have more than one?
Meh, I’ve got bunches of ‘em, none particularily fun. There’s ol’ Veronica and her stigmata, Gregory the great who went on to be pope and one of the Catharines who was known for how spectacularily unspectacular she was.
Where are the really freaky ones who were ripped apart or never took baths? I want one of them!
St. John Chrysostom
*John Chrysostom’s preaching, by word and example, exemplifies the role of the prophet to comfort the disturbed and to disturb the comfortable. *
“What is nobler than to mold the character of the young? I consider that he who knows how to form the youthful mind is truly greater than all painters, sculptors and all others of that sort” (St. John Chrysostom).
As a high school debate teacher, I kinda like this guy! 
There’s a patron saint of difficult marriages? You’d think she’d be absolutely run off her feet.
Let’s see, by combining my names and careers…
one with two feast days, March 19 and May Day: Joseph, husband of Mary
one that is NOT a once-living person: Archangel Raphael
and one that is very clear WAS a real person: Thomas More
And going for my avocations and past work, I’d also get some leverage from Archangel Gabriel, and one not-yet-saint, the Blessed Fra Angelico.
Not bad, after all.
For most Catholics, your patron saint is arrived at by onomastics. Traditionally, your parents give you a Saint’s name upon Christening, and they, or you if you’re of age, may choose another one upon Confirmation, to invoke those Saints’ good traits and ask their intercession for you. These need NOT be your everyday-use name: you can be Dweezil Xavier Michael Jones or Wildflower Magdalene Dymphna Smith and even your Priest know and address you primarily by “Dweezil” or “Wildflower”. In some Catholic cultures you are customarily placed under the protection of the saint that is commemorated on the day you were born or the day of your christening, but that’s not mandatory at all.
You can also have a saint assigned to your Situation/Occupation – If you’re an artilleryman, you are under the aegis of St. Barbara; a TV technician, Clare of Assisi; a news anchorman, Gabriel; if a librarian/information scientist, Isidore of Seville. And so on.
For non-person entities like countries, you can have the entity specifically placed under the advocacy of a particular patron by the Church. Or, an individual becomes a devotee of a particular Saint.
Technically I’m an attorney, but I’ve never worked professionally as anything other than a writer or editor. Looks like I’m going with St. Francis de Sales.
Upon reading the bio, I see that St. Francis was also a lawyer-writer. I guess there’s a saint for everything.
My patron saint is the same as yours QuickSilver
I say we canonize Cecil and make him The Patron Saint of Truth and The Straight Dope.
Or you can adopt a patron saint when you’re confirmed. My feast day was two weeks ago, but it didn’t get noticed here.
FWIW, I notices St. Polycarp while browsing the list and immediately thought of you. Then I noticed he was the Patron Saint of earaches. Not as sexy as some of his better known compatriots… but still, next time I have an earache… I’m coming to you.
