From this record on the 1790 Census, it would seem that George McMichael was married by then to a wife --probably married to [Ursula about 1760/61] and had one daughter [probably Ann McMichael born 1763]and showing George McMichael, Sr. as head of houshold with three sons [probably George McMichael, Jr. born 1765; and the twins, Henry and Jacob McMichael born 30 Nov 1767.
And John William Leysath/Leysaht is head of household with a wife and this is probably the Johannes Leysath born 2 Sept 1753 [(#171)baptism 23 Sept 1753 Book of Record- Giessendanner] son of John William Leysath and his wife Ursula Giessendanner. It would seem that the first John William Leysaht died earlier than 1760/61) and thus Ursula was then a widow to marry George McMichael.
