Genealogy is a team sport! your Mom worked what I call "boots and notebook", not the Internet resources available now...
It's because so much of my harvest is from a crop, I neither planted or tended. I give charts out for free, as your Mom did. Giving in the same spirit, as I recieved. I did the Scottish portion of our branch, so it has both LDS and GROS references.
while I'm almost finished with the Scottish portion, I promised my hubby Bruce, that I'd finish putting together one country before beginning another, it is impossible, so I am working on England (which is soooo expensive)while writing my part of the Scottish book.
I intend to post everything to the LDS when I've published.
I hope that would please your Mom in honor of all she did and gave me.
I'd give you a copy of our branch if that would aid you.
