I am related to Magdalena, her parents John and Ketherina, and apparently you also. I am a decendent of the John Eslinger line, and John D. Eszlinger was my GG Grandfather, his son John D. Eszlinger was my G grandfather, and his son Enoch Eslinger was my grandfather. John and Katherina are burried in Lodi, California.
As you can see, there were many, many spellings of the name Eslinger. Esslinger, and Eszlinger are all of them.
You are in luck! I came across this post cause I am neck deep in research right now on family members past my GG grandfather.
Drop me a line, and I will be glad to share all the information I have with you.
