Happy Mother's Day!

I'm probably the only person you know who marked at least part of the day in contemplating mitochondria.

Abbreviated "mtDNA," it's the part of your unique genetic code that was inherited exclusively from your mother. And, she inherited it exclusively from her mother, and so on, and so on, ad infinitum.

Anyway, from a genealogical standpoint, it is much harder to trace these maternal lines--at least in western cultures--because surnames change with each generation.

I've only been able to trace my own mtDNA back to an Irish emigrant named Elizabeth Gallagher, who lived in Brooklyn, New York, in the 1850s.

My dad could trace his line to a Sarah Brown, who was born in the old Fairfield District of South Carolina in 1768.

And, my cousin Joanna can trace hers all the way back to 1600s Connecticut.

Well, before I get off on too much of a tangent, I hope those of you reading this in the blogosphere take time today to think about the unique things your mom passed on to you!

Oh, yeah, and two words for my mom: Ham and Cheese!
