Joseph Ulrich Mishler (Mischler), I b1715 - Question regarding Joseph

I see where a man named Joseph born circa 1729 is listed as Joseph's father, and it says Joseph wasn't even born until 1715.

Also, the Overview says that Dorothea was born around 1715 but the Geni page for her says 1702. It also says Joseph was born around 1700 but his Geni page says 1715. If they married around 1728, as stated in the Overview, I imagine neither one of them were born around 1715.

I am hoping anyone that knows the correct dates of their births, as well as Joseph's father's information, etc. can let me know. I am trying to find this information as well.

Thank you!
