To those of you who study genealogy/family history, what was the most interesting discovery that you made while doing your research ?

Soooo many things. Most of my father's family are from Gloucestershire in England. I still have 5th cousins living there, and one of them moved HERE! When I was 13 we visited them! We saw the family farm where my great great grandmother Selina Daniel was born, and later taken over by my great great grandfather! We visited the graves of as many of my father's ancestors as we could find. He became quite an anglophile!

Through my mother's side of the family I am connected to 23 of the original Pilgrims who founded Plimoth Colony! AND NOW I actually LIVE in Plymouth, Massachusetts, and the forefather's monument with all their names is right behind my apartment building on a hill! The old granary burial ground is about a mile down the street, where some of them are buried!

My cousins traced my dad's side back to England as far back as the late 1500s. Then for some reason we don't exactly know, some family members changed the spelling of the last name in the mid 1600s, and sailed west to Virginia. They migrated south into the Carolinas, and eventually to the midwest. One of my great grandfathers many generations removed (cannot remember his name) was a state senator in North Carolina back in like the 1820s. Another great grandparent many generations removed, was Flanders Callaway, who married Daniel Boone's daughter. And I'm a distant cousin to Bart Starr. That's all I got.

My great grandma had so many children pretty much making her pregnant every year for over a decade of her life ( late 20s / 30s era and through the war)

My nanna on my mothers side use to be a land girl during the time of WW2

My nanna on my fathers side of the family used to be close friends with Mr Beans mother.

There are so many things going back to the 1500's in England. The most fascinating thing to me was shameful. My great-great-great grandfather and his son fathered illegitimate children with the same woman. At least the older man raised the child as his own, but it is unknown how his wife felt about that.

That my apparently Welsh family only goes back 3 generations before arriving from England. Then I find a great great grandfather 'baptised' in a famous local church in my nearest city!

My mother is Icelandic. We've traced her lineage back to The Landnám.... a settlement of Iceland 874–930 CE.
Back when Norse families crossed the North Atlantic an claimed land by fire and oath.

The town I live in now is the town my family has lived in for centuries tracing back to a marriage between an Irishman who built clipper ships and a native American woman.

That my great grandmother and one of my early girlfriend’s great grandfather were brother and sister.

That there was s major cholera outbreak in the eighteen forties, that destroyed half the village.

The beauty of the town my Grandparents are from.

An ancester was a Sgt. with the 28th Pennsylvania Volunteers, and died at Gettysburg

An ancestor on my father's side was thrown out of England for stealing horses

That a great uncle was a WW1 war hero and a convicted bigamist with a handful of wives and even more children.

That time in Europe when most women were murdered. Recently enough to see the dates in The DNA of today.
That all Italian Jews descended from a single female and thousands of men for hundreds of years.
That 160,000,000 native Americans lived where the USA is now at about 1500 AD.
Nothing you want to know. And probably not anything anyone here can ever engage with. The enemy spoke through the DNA.
