I don't know if I ever responded to this query. It is obvious I did not via GenForum. I thought that I might have via email, but if not I am very sorry.
First, I can find not a record of a Rueben Mauger anywhere. Next Frederick Mauger b: 6/14/1788 in Pottstown, d: 1869 in Etna, Licking Co., OH., son of Heinrich, married Elizabeth Nagel. Elizabeth died before 1831 and I have no children listed for Frederick nor a 2nd marrage, so I don't know about your Frederick and Hester. I can find no 1850 census for Frederick in OH. I subscribe to the ancestry.com census service and it does not have one. There is one for 1840 which does not help me a bit. What is the age of Frederick in 1850?
There was a Samuel Mauger b: 3/19/1840 in Pottstown to parents Samuel and Susanna Mauger.
My line descends from Heinrich's son Henry via Henry's 2nd wife Catherine Nagle. From there to Jeremiah Nagle Mauger to David B. Mauger, my g grandfather.
I was born and grew up in Baltimore, Fairfield Co., OH, and although I don't live there now, I get back quite often.
As Frederick has really been a blank spot for me in Heinrich's tree, I look forward to hearing from you.
