I have Isaac and Mary Keller's children listed as Peter, John, Michael, Elizabeth, Isaac and William - no Hannah or Henry. Peter (1826-1910) m Jane Youngs and had one son I know of, Sidney (b 1871 in Roblin, Ontario). John (1822-1899) m Hannah Meeks. William (1831-1870) lived in Madoc, Ont. and is my connection to this family. He married Nancy King and had children Andrew, Almeda (my GGMother), Phoebe, and Margaret Victoria. Isaac Johnson Asselstine was b 1847.
