Hi Matt: Tried the link at the end of your message and couldn't get it to work. I think we have corresponded before, or perhaps Herb Gillham had mentioned you.I am a descendant of Robinson Robert Gillham through his son Robert A. Gillham. Robert A.'s son ( I think) married Jane Barber1/21/1847 in Hancock, Illinois.
I would like to access your further information and sources, if you are still willing.Of course, anything I have that is interest to you, I will share.
