I saw this post further down on the list, and thought that I might add some of my own info.Part 2 will include some info on a few VanDerslices of Philadelphia.
My 3rd great grandmother did a family history of the VanDerslice / Roberts family in Sept. 1862.It consists of only three pages, but it is packed with tons of information.
According to her work, she quotes a History of teh First VanDerslice in Holland, Taken from a work on Dutch Heraldry in two volumes in the Dutch Language.
"The first Van der Sleize was found by a nobleman's wife lying on a beach of the North Sea near or in the city of Groseingen, Holland.He was adopted by the family, but could not take their name.They, not knowing his right name, gave him the name of Van der Sleize, meaning - From the sea Beach.He grew up in their family and married their daughter.The father and mother died and left him and his wife their estate and title which was the father's, he being a Baron.The crest of the Baron was an Arm with a Coat of Mail on it and a dagger in its hand striking downward.The Baron Can der Sleize on taking his title was given as a Crest a Shell representing the place or beach where he was found.He amassed a fortune and was very charitable.For his charity, which was very great, he was endowed with the Cross of the Legion of Honor which was put on a Shield (Dutch) in addition to his Father-in-law's Crest and his own, and the motto 'Sans Crainte' to constitute his Coat of Arms.The motto means 'without fear.'
She went on to say Reinhard or Reinier Van Derslice (Van Der Sleize) was the first one that came to America from Holland.Children of Reinier Van Der Sleize were -- Arnold, Johannes, **Anthony** and others.
Anthony married Martha, daughter of Heinrich Pennebacker and Eve Urmstead, daughter of Hans Petier Urmstead, son of Nicholas Urmstead who died at Crefelt on the Rhine about 1680.
Anthony's children were: **Henry m. Catherine Sosamanhouse** Eve m. Peters Ann m. Herman Urmstead Anthony m. Elizabeth Pennebacker daughter of John, son of Heinrich Pennebacker
Henry VanDerslice, son of Anthony VanDerslice, born the 9th day of March, 1726, was married to Catherine Sosamanhouse the 23rd day of October, 1750.He was sheriff and Surveyor in Reading, Bucks County, Pa. in 1787.
Henry and Catherine's children were: Anthony b. June 4, 1753 Henry b. Apr. 17, 1755 Jacob b. Feb. 7, 1757 Daniel b. Feb. 17, 1759 Catharine b. Nov. 10/15, 1761 Sophia b. Mar. 10, 1764 Margaret b. Jan. 24, 1767 John b. Mar. 31, 1770 **George b. Oct. 8, 1771** Joseph b. Jan. 28, 1776
