I realize your message was posted 4 yrs ago but I just "stumbled" upon it. I have a Sarah Carr b abt. 1840 in IN who married Samuel D. Isenburg (however their name was also Isenberger, Eysenberger, etc. etc.) they were married in 1861 in Peoria, IL and moved to Kansas ca 1876. I have a lot of info on the later Isenburgs as Samuel D. was my gg grandfather. I could furnish you with this if you are interested. I have nothing on the Carr's other than that Sara's father was William b ca 1815 and would appreciate anything you have.
