For what I have gathered, a Conrad MANN arrived in PA and is found on a tax list of Manheim Twp, PA in Dec. 1771. He had four sons, Conrad, David, George, and John, all who used the spelling MONN. Another Conrad, son of David Jr, David Sr, Conrad (above) used the spelling MAUN.All part of the same family but for reasons unknown at this time some used different spellings.I also have a John L. MOHN b.1906 with a son named Robert William MOHN b. 1925.I have nothing more on them.Any information on these surnames in PA area would be appreciated. I'm mainly looking in MONN but would like to find more on the other names as well.
