So, you are asking, who are the parents to NICHOLAS GERMAN? When and where was he born?
You say he was born in Saratoga County, New York, but you're not sure and don't have documentaiton.
Probably Nicholas was born circa 1800, since his oldest child was born circa 1825. If that's true, the answer to his early birth may lie only in New York (and not online). You may want to post your question on the New York forum.
Ancestry Message Boards offers boards specific to a county (such as Saratoga County). There one can sometimes find local volunteers, willing to do look-ups in early county records.
Also the county genealogy society may be blessed with volunteers willing to do look-ups in local records - such as the churchbooks in Half Moon, Saratoga, New York. What religion was Nicholas?
Possible parents and ALL OTHER information below per Ancestry.com family tree and not verified by me. An online tree can be wrong in any one detail or in many details but still provides useful “hints” as a starting point.
You might try corresponding with the person who made this tree. Do you have a subscription to Ancestry.com so that you can do that? If not, you might post a request specifically for that - asking someone on GenForum with a subscription to contact that tree maker.
Just brainstorming here - since this will be a tough one.
