Good Heavens Spidermonkey, you're doing me a great service. Yesterday I had no idea about the existence of the Cartwrights, now thank to you I'ˇm building a whole new branch of the tree! I've ched the webpage you've mentioned, the dates would imply that Montillion Sr was born around 1736 and died in 1810; his widow Sarah (I expect there's no chance of knowing her maiden name) was born in 1753 and died in 1828. Any info on the other children (whether they married, or when they died?). By the way, do you have any idea about Samuel Morris's parentage?
I am most thankful to you both for all your help.
