With the exception of an Ott that I have been unable to trace back to Germany from early 19th c. South Carolina, the rest of our family is exclusively British - mostly Scottish and Irish with a heavy admixture of English and a sprinkling of Welsh.
The frightening birth defects out there for those of us of almost exclusively British ancestry are the neural tube defects (spina bifida etc.) We watched the kids in utero like hawks for that one . . . and I took folic acid until it was coming out my ears. Thank heavens both born free of that trouble.
Have not hear those names. This is not an exhaustive list but these are the most common names I have encountered in my 13 years with these people:
Martin, Miller, Byler/Beiler, Fisher, Oberholtzer, Brubaker, Nolt, Zeiset, Ebersol, Yoder, Detwiler, Stolzfus, Fisher, Mast, Bender, Beachy, King, Kauffman, Horning, Wenger, Gingerich, Hostetler, Schmucker, Noecker, Aungst, Zook, Lapp, Zimmerman, Noll, Swartzentruber, Weaver/Weber... there are more but it is getting late....
