I am relatively certain you are referring to Cassandra Arrasmith, married to William Crumpacker.William's 1st American ancestor was Hans Grumbacher, christened in 1707 in Sumiswald, Switzerland (where the name was spelled "Grundbacher"), emigrated on the ship "Hope" 28 Aug 1733 through Philadelphia, married Elizabeth #1 (there were 2 Elizabeth's), and died Dec 1744 in Chester Co., PA.Hans' tombstone spells the surname "Grumbacher".Hans & Elizabeth's line to William Crumpacker is:
Hans Grumbacher + Elizabeth #1
Ulrich Grumbacher + Barbara Light
John Crumpacker + Elizabeth Unknown
John Crumpacker + Elizabeth Hewitt
William Crumpacker (b. 5 May 1818 Botetourt Co., VA, d. 5 Apr 1862 Sullivan Co., MO) + Cassandra Arrasmith (b. 20 Aug 1823 Bourbon Co., KY; d. 20 Jun 1893 Garfield Co., WA).They were married 21 Dec 1843, location unknown.Cassandra's parents were John Richard Arrasmith (1799 Bourbon Co. KY - 1880 Sullivan Co., MO) + Nancy Wood (1795 Clark or Bourbon Co., KY - 1872 in Sullivan Co., MO).John Arrasmith & Nancy Wood were married 1818 in Bourbon Co., KY.
Some time after William Crumpacker's death Cassandra & children migrated to Washington State.The kids were:
Henry (b. 25 Oct 1844 in MO & d. 24 Apr 1924 in Orfino, ID)
Nancy (b. 15 Jan 1846, probably MO & d. 27 May 1883 Garfield Co., WA)
Elizabeth (b. 1847)
Lavina (b. c. 1850)
Phoebe (b. 1852)
Edward (b. 1853)
David (b. 30 Sep 1856; d. 10 Jan 1907)
Anna V. (b. 1857 Sullivan Co., MO; d. 14 Jun 1874 Garfield Co., WA)
William Thomas (b. 1860; d. Oct 1928 Walla Walla, WA)
Martha (b. 20 Jul 1862 Chillacoth, MO; d. 27 May 1935 Lewiston, ID)
Mary (b. 20 Jul 1862 Chillacoth, MO; d. 1944)
David, William Thomas & Martha married the Tewalt siblings: Mary Elizabeth, Rebecca and Isaac, respectively.
For the Arrasmiths, like the Grumbachers/Crumpackers/Crumbakers, they were German Baptist Brethren in the 1700's.I'm not sure where they originated, but I feel pretty certain they were originally from the Palatinate in Germany/Switzerland.I also don't know if they started out in the Chester Co., PA area as so many of the "Pennsylvania Dutch" did ("Dutch" being a corruption of "Deutsch", which is German for "German").A lot of the Pennsylvania Dutch migrated south, first to Frederick Co., MD and Loudoun Co., VA; and then some went into the hills of Virginia, to Botetourt and Augusta Counties.From those two counties many of the Brethren migrated into Kentucky.
As for the art supply Grumbachers, though there may be a connection back in the Old Country, there is no descendant connection that I am aware of from Hans and either of his two Elizabeths.All of Hans' descendants now use one of the variations Crumpacker, Crumbacker, Crumbecker, Crumbaker, and one or two less usual variations.
I have a little bit more on the descendants of William and Cassandra, but not much.If you would be willing to share info, I would love to hear from you.
