Yes, I did have the twin who lived just 1 week.
I think you meant "Catherine GELLING", not "Catherine GELL". She is the second daughter of the John G in the Subject Heading. I gather you are related to her?
I haven't taken this family down beyond identifying the children of John Moore and Catherine Gelling who married in 1850 Santan, so you've added some things for me. I think the "Ellen Moore" in the census will be Sarah Ellen Moore, who is the twin of Esther Christian Moore b 1863. She also died early, and is in Brian's index as buried 9 Sep 1889 Santan age 26.
