Have some children listed as being his but cannot find any source for this info. Is there a will or other document to show, first, that his wife is Margaret ? and second, that his children are: Barbara, Elizabeth, John Michael, Daniel, Christopher and Madelaine?
1768: Land record of Simon & Margaret Hart to Andrew Site 168 acres Buffalo Creek 1771: Land record of John & Elizabeth Mitchell to Andrew Sites (Seitz) 178 acres Dutch Buffalo Creek.
1790 Census: 4 males over 16, 4 females. This is the right number of people but does not match up with the census. For example, Christopher (unless a brother to Andrew)and John Michael are enumerated in their own right, so who would the other 2 males be? Is there some other record, will, etc that tells the children's names or this an unsourced tradition?
