My grandfather’s second wife adds to the Pennsylvania Dutch lineage, both through her parents and her first husband.
Edna (January 1, 1902-1994), was the daughter of [Fawre?] Hefelfinger and Cora Alice Holsinger.
Hefelfinger, it turns out, originates in Diegten, Baselland, Switzerland. A Bartli Hefelfinger (before 1565-before 1640) has son Martin (July 7, 1594-September 8, 1672), who has son Johannes (April 16, 1666-January 11, 1737), who has son Martin (September 26, 1699, in Switzerland; March 25, 1742 in Heidelberg, Lancaster County, Pennsylvania).
Holsinger, especially, is prominent in the Brethren, including the old order around Covington, Ohio.
And Huffman turns out to be another of the Brethren names.
