I'm a descendant of Eleanor Hutchinson & William Metcalf of NYC. I've no proof that your Absalom is related, but the circumstantial evidence says that Absalom was Eleanor's brother (court papers naming Absalom as William Jr.'s uncle), and Eleanor's death notice in a NYC paper names Alfred Winans. Other researchers say he married a Mary Ann Hutchinson, so I'm guessing that she's Eleanor's sister.
Are you a member of Ancestry.com? If so, search on Absalom Hutchinson, b. 22 Jun 1793, Ireland, d. 01 Apr 1879, Pennsylvania (Bradford, McKean Co.).
I have no original research. Mark Darrin Martin (he's actually a 3rd cousin of mine descended from William Metcalf) has posted an 1879 Bradford PA newspaper article transcription, which is the closest I've seen to any history. (http://trees.ancestry.com/tree/16674338/photo/d26b5e79-0d58-...
I suggest you look for Absalom's descendants, who may more info that is not posted online.
