I'm not sure how Jim ties in - Do you have a tree that goes from him to this Valentine?I have seen trees of some of the Allens from this area, just nothing direct.
John Allen in Harrison IN has been claimed for 40 yrs by Alvin Allen as the father to Bailey Allen in Grayson Kentucky (not VA) and Alvin's Grandfather is Valentine Allen b 1854 and Susan Wilson.This Valentine was in Pulaski Missouri in 1860.Bailey's death certificate lists John and Polly as his parents.
Carr Allen ca 1780 was married to Dianna Oller is said to have been a son of this John.He died in Hot Springs AR probably between 1849 when he bought land there and the next census in 1850.
Me and Barbara Reynolds are digging in this stuff right now.Her line is from the Ollers that married into the Allen family from Grayson Kentucky.So far there is tons of documentation from some of the collateral lines of those Ollers as well as the Allens.
We are still out to lunch on Hezekiah and the other Valentine though, that's why I'd like to see Jim's lineage.
