2.  1850 Census Every-Name-Index/Images (online at Ancestry.com, Image #34 of 64):  Bern [Berne] Twp., Fairfield Co., OH, Roll M432_677, p. 447B, 219/237, enumerated 15 Sep 1850, official enumeration date 1 Jun 1850 (extracted by Diana Gale Matthiesen):

Quinn James	33	M		Laborer		Ireland

Jacob is out of order, which usually is intended to indicate the child is the offspring of a prior wife.  I wonder… how solid the the marriage date?  The adult Catharine is Henry's sister.

Henry is Eleanor's son-in-law, not his son.  In other censuses, Eleanor gives her birthplace as New Jersey.

In the column for Anna's mother's birthplace, it looks like the enumerator started to write an "N," then wrote over it with "Connect.," which of course is wrong.
