Nathaniel Wallace 1747?

This guy pops up occasionally as the father of some of John's kids. I have found a census report from Cecil County Maryland (near Delaware) that gives John and Geneva Jane six kids living with them, and we know that probably William, the oldest, is no longer living with them, whether he was born in the US or born back in Ireland as the rest of them were. We know that John Jr. (1788). and Robert (1796) are pretty much in that household: born in Ireland, came over with John and Geneva Jane in 1797 or 1799. Who are the other four?

Some people in Ancestry found a Francis (1784), a Mary (1794), a a Jane (1790), and an Adeline (different dates); it was in digging into these that I found Nathaniel. One guy claimed that even Robert was Nathaniel's, but also Mary and Adeline.

I found a census report for Nathaniel that had him living with a wife Mary and a daughter Mary - could be a Mary that is attributed to John. He was living in Allegany, Maryland, way west. The thing is, he's probably John's brother, an older brother. He is not one of the four that originally were supposed to come together in 1770 (a doubtful story) - James, William, Hugh, and John - but he was of that family and supposedly born in Glasgow.

One guy has him married to Geneva Jane and while some of his kids are all his, some have half brothers. More likely he just married this Mary woman and Geneva Jane lived and died with the family of John. Unertain family, but her own.
