I am also researching this family and I have some information to add to yours.I do not have the parents of Michael and Dorthea Uhland or for Adam Nace b. 28 Feb 1770 but there is some posting on World Connect about Adam's parents.The following is what I have to add:
1810 census PA/York/Codorus
John Oulandmales, 00011females 00001
(it appears Michael and Dorthea Uhland was living with John.
Next in census:
Adam Nacemales20010females 22110
I can not find John Uhland after the 1810 census.
