I have made up a chart and table that may help when looking at your DNA matches. I am sure I did not explain it very well, but I did try. LOL
I made sure to add an extra generation due to to fact of large families, and there being such a large age difference between the oldest and youngest child. Which can be a generation or a generation and a half.
It is a pdf file, I hope this helps a little bit when looking at matches and wondering where the connection may lie.
I was able to upload it at the "Online Support Community" which is in the collaborate tab at the top of this page.
The tilte is the same as this post "Chart and Table for Ancestry DNA matches"
