I also use the website FamilySearch.org and the website "Myheritage". Interestingly these tools both have information on Jacob Weinmann (*14.01.1669 in Sielmingen) but with differing information regarding his parents. I will show you what I found:
Johann Georg Weinmann (I found his dates in the archive of Sielmingen, Filderstadt)
*05.09.1735 +11.10.1821
Michael Weinmann (I only got his name from the archive; but FamilySearch.org lists him as Johann Georg Weinmann's father with the following birth date)
*13.09.1703
Jacob Weinmann (FamilySearch lists him as Michael Weinmann's father with the following birth date)
*14.01.1669
Now FamilySearch.org names Hans Weinmann (*23.09.1638) and Catharina Bayha (1639) as Jacob Weinmann's parents (differing from current Wikitree information, but without providing sources.
While MyHeritage names Hans Weinmann (*1636-1690) and Margaretha Weinmann (*1644) as Jacob Weinmann's parents.
May be you have an idea how to make sense of that?
