Hi! I've been looking for Henry Bradley Alden, too.Did you know he's a descendant of Capt. David Perry (a Lt. in the Rev.?He wrote his memoir in 1819 (pub 1822) and it's incredible!Are you a descendant of Henry Bradely Alden?He's the son of Dr. Isaac Alden of Cornish,Sullivan,NH (if were talking of the same person).His mother Hannah Perry was Capt. David Perry, whose ancesters go back to Sandwich, MA.My source says that Henry Bradley Alden "went to IL, married and had a family."E-mail me if you'd like to share information.
