Thanks for responding to my message. I tried to email you but it didn't work. I have since found some information about Robert Allen. His middle name was Bell and he was born April 8, 1817 in Davidson County, Tennessee. He died November 23, 1847 in Greene County, Illinois. His wife Susannah was born February 25, 1819 in Tennessee and died July 28, 1854 in Greene County, Illinois. They were married March 12, 1840 in Tennessee. I don't have anything on her family, but I have Robert's line going back three more generations. I don't have anything for a Zechariah Allen either, but maybe he is a brother or something. I don't know of any of the siblings, so it could be.I have this information from a relative of mine who is researching this line and looking through birth and death records and other documents, so I consider it fairly reliable.
