My (Samuel) Allen Memorial Book has Samuel Allen and Hannah Miller m. July 1, 1730. Their son Noah the 2nd of8 children is mentioned. It states:
"Noah, b Sept 12, 1734. He was the First Lieut. in Capt. Moses Saut's Co., which marched April 2, 1775, on the Lexington Alarm; promoted to be Captain Oct. 1, 1776; on Dec. 6, 1782, reported sick at New Marlboro."
It says nothing of his marriage to Sarah Knapp or his child Noah who married Elizabeth Learned Partfidge as you list.
The book continues the family line on this Samuel only for the 5th child Ebenezer b. Oct. 17, 1743 in Northampton, Mass., who was a Colonel in the revolution and married a Lydia who died in 1834.
This is all I have, not much help, sorry. I assume Noah was married, but at the time of my books writting(1907), I guess little was known or was not sought about his wife and children.
