John and I have already been in contact.We well may be related, but he is checking names etc. with other family members to verify. The information on Barnaby Fallin is great!I've been looking for David's parents for some time now.I'd love to know what additional information you might have including sources and earlier ancestors.Feel free to email me privately if this is too extensive for bulletin board posting.
David Fallen remains elusive.From the sketchy information I have, he may have been married as many as three times.I am not sure how much of this is correct - more work definitely needed here: 1) Mary Willey 11 June 1791 in Dorchester MD.She may be the mother of his two eldest daughters Elizabeth and Mary; 2) Esther Summers Perkins 29 May 1798 in Somerset MD.Esther may have been the young widow of John Perkins who she married in Somerset Co. ca 1791.He was lost at sea in about 1793.She might also have had young son when she married David Fallen; 3) Sarah Payton 14 April 1844, Bracken KY.In the 1850 census, there is a widow Sarah Fallen, age 50 listed.She is not living with either of David's sons.
The J.S. Fallin in Clermont OH in 1840 is likely David's son John.I believe his middle name was "Summers" after his mother Esther's family.I don't know much else about this line so I can't be certain, or about Ellen and Mary/Maria in Hamilton, OH.
Finally, your information on Illinois Fallins who served in the Civil War matches my own.From the 1850 census, known sons of Henry Fallen (s/o David) were: James; Benjamin Franklin; Henry Clay; Jacob Stroube; and David Alroy.According to the Illinois Civil war Veterans Database, Benjamin, Henry and David all served as musicians in the 48th Infantry (HQ).James and a Barton Fallin were privates in company K of the 79th Infantry. Finally there are two entries for a John W. Fallen in the 37th Infantry.I am not sure how John W. and Barton might fit into the family, but they could be older brothers, gone from home already by 1850.Given the naming practices Barton could be a variation or mis-trasncription of Barnaby?
