I know the names of all 8, of which only 2 were born in the US. For one of them I have a photo and know a fair amount about her--she had 12 children (of whom only 4 were still alive when she died). My great-aunt was 15 when she died and told me a number of stories about her...very old-fashioned and very religious, married at 17, not likely to have gotten into much mischief.
No offense to your gg-grandmother (or mine) but most of us have something to hide and I think that’s always been true. One need only stumble once to add something to the family gene pool
