just seen this post as it mentioned my third great grandmother and just wanted to correct some info you had, her husband william cass was from Huntington in Yorkshire and was born in 1827 to thomas and Ann and married Sarah Chapman daughter of John Chapman from all saints York in the 1850`s they had several children Sarah, Jane, William, Harriet and Mary as well as my direct descendant Thomas Chapman Cass. The family moved to Liverpool where some stayed and some moved to America. From my Research i have found that there are two prominent areas for The cass family, One being Mine in Liverpool and the other being Lincoln due to one of thomas and annes other children called Thomas moving to this area. i know this post was initially written a few years ago but i hope you still read this site
