Very interesting post. Court records show that Jeremiah Allen's father and James and Richard Allen's father's brothers and sisters. James birth date was 1800 and was a cousin to Jeremiah. The family always heard they were from the Ethan Allen and the Green Mountain boys line. That would have been a major Northern line. If my information is correct Jeremiah is Also related to the Taliferro Stribling, George Washington, and Francis Wright lines. I huge North South conflict. The Battle of Fredericksburg destroyed Jeremiah's Double House directly across the river from the shelling. There is a painting of the Union soldiers using his house after shelling it as cover at Fauquier St and Caroline street in Fredericksburg. Jeremiah's father was Sylvanus d. 1818 and Molley d 1843. I think Sylvanus was name change to disconnect the line. He shows in Essex Co, Va censes in 1810.
