Jacob Schwerin--Lost Son Found

Earlier, I wrote about Jacob E. Schwerin (born 1855), my sister-in-law's third great grandfather, who was from Sumter, South Carolina but did not appear on any of the many online family trees for the one Schwerin family from Sumter--that of Julius and Caroline Schwerin and their children.  There are many mentions of Jacob Schwerins and J.E. Schwerins in South Carolina in the 1870s and 1880s, but I wanted to find something definitively linking him to Julius and Caroline.

There were several things that I was able to find that alluded to Jacob's being a son of Julius and Caroline Schwerin.

Jacob E Schwerin--What Else is Known?

Earlier, I posted about my sister-in-law's third great grandfather, Jacob Schwerin, who seems to have magically appeared as an adult.  So what else do we know about Jacob?

Looking for Jacob Schwerins in South Carolina, I found reference to a Jacob E Schwerin who suddenly appears beginning in the late 1870s in Wedgefield, a village in Sumter County just west of Sumter proper.

Jacob E Schwerin, Who's Your Daddy (and Mommy)?

My sister-in-law's third great grandfather, Jacob Schwerin (b. 1855), seems to have appeared out of thin air.  He and his wife Amelia Kaufman had two children, Nettie (b. 1885) and Monie (b. 1886) in Baltimore.  The 1900 US Census (the last before he died) stated that he and both of his parents were born in South Carolina.  His marriage license (found at the Jewish Museum of Maryland) was more specific:
