George, we do have a match. My family hard back book published in 1950 is titled The Ham, Hamm, Hamme Family in America 1748-1950. The dates and information on Cassie and Henry appears to me more detail than yours. I show Generation 4, Family 3 Susan Hamm, third child (3 of 9) of Conrad and Elizabeth Overland Hamm, was born in York Country, PA, 31 May 18 29, died 2 February 1908, married David Krout, born 19 October 1826, died 25 March 1891, York County, PA. I have all the information back to Daniel Ham.
Daniel Ham was born in Germany in 1728 and died 14 December 1794 in York, PA. Daniel took passage on the ship Hampshire at the port of Rotterdam, Holland, and arrived at the port of Philadelphia, 7 September 1748. Daniel located near Jefferson in York Country Pennsylvania. According to the gravestone inscription, his wife's name was Barbara and she was born in either 1726/1736 and died in 1792.
Do you know who Mrs. D. E. English is? I have a 30 year old letter asking about Susan and David as they are her ggparents?
I will trade you a copy of my book for an electronic copy of your information. Suggest you use my contact information in my original posting.
