This is what I have (written by Amos Seldomridge in the 1940's).
Baltzer Seldomridge (b. abt may 25, 1755 d. 1815 m. Catharine Lautermilch d. 1828) was the son of George Sr. and George's second wife, Anna Mary Cayunta (Cunigunda).George b. abt 1727 d. Oct 4 1788
Baltzer was grandson of Andrew Seldomridge (Andreas Zeltenreich) and Anna Maria last name unknown.Sometime before May 16, 1717 Andrew Seldomridge settled in Conestoga, Chester County, PA (Lancaster County was formed out of Chester County in 1729).The family moved and finally settled just outside of New Holland, PA.The Zeltenreich Reformed Church is where much of the family is buried.Andrew is believed to be there, also, but I have not found his grave since the old stones are completely smooth.
This is what Amos has written about Baltzer:
On the death of his father, George, he inherited fifty-five acres of land on the west side of Mill Creek.He sold this land and moved to the Shenandoah Valley of Virginia.The LOWDERMILK (LAUTERMILCH) family, a neighboring Mill Creek family, went to Virginia and settled near Baltzer.
It is not known what year Baltzer migrated to Virginia.In 1786 his name appeared on "A Return of Captain Henry's Company" in Pennsylvania.In the 1790 Census Records for the US, Baltzer is not listed in PA or VA.But on April 8, 1790 in Augusta County, VA, Baltzer's name appears on the tax lists.In 1797 he purchased from Gordon and Ann White, two tracts of land each comprising 120 acres making a total of 240 acres.This plantation, lying on the South River, was part of a tract of 243 granted to Isaac White by patent dated September 20, 1748.In 1801 he is taxed for 170 acres of land and in 1810 for 128.The plantation being 10 miles southwest of Staunton, Va and adjoining the land of Isaac Moore.Baltzer apparently died in 1816 since Catherine is listed as owning the land in 1816.By the year 1818 the plantation had decreased to 111 acres and is called Providence.Sometimes the place is called Hermitage.Catharine held most of the land while she lived.At her death it began to disappear.By 1834 most of the land was gone.
My husband descends from Baltzer's brother, George Jr.
