I am including the daughter’s profile. archive.org has tons of references as he was one of the first settlers of Germantown and maybe should be a notable or penn project profile. Please see references under daughter for proof of relationship and link to Germantown and first settlers.
I would like to set up a profile for Herman if he is not already existing.
Also is this the same Sytge married to Huppert?
