That's the next step - find those children 10 years later.
This query began because I have a DNA link with someone in the US who is the great grandson of Ivy. So it seemed the simplest to discover Ivy's origins to see if anything obvious popped up. But nothing's simple is it? The link could well be on his paternal side instead, but that's even harder since his father was adopted.
So I now know what to do with the next bad weather day (or two).
