I think you must have the wrong Margaret if I'm honest. That would mean that she had 4 kids to 3 different guys? I'm confused that she's your ggg grandma and your 58 she's my ggg and I'm only 28? I just assumed that if you were posting these facts the now that you'd have a census or death/birth Certs etc on your pc to email to me
:-) I'm not 58, I'm only 53..... My kids
As you will see from the note above, Margaret was 16 when she had my GGGrandmother, but a wee bit older when she had yours. After four generations there can be a "timeslip" so that whilst my oldest son is just a couple of years younger than you, we may share the same generational relatives.
Indeed, cos of large familes and oldest/youngest stuff I have one grandfather, born 1899 and who served in WW1, alongside his great uncle born 1885......
