Hello, my name is Rachel Addicoat, a descendent of William Knopp and Jane Vale through my great-great grandparents James Knopp and Sophia Lydia Clay, whose daughter Florence was my great-grandmother. I am looking for any further information about William Knopp and Jane Vale (apart from what has already been posted) plus I am looking for information on Eliza Knopp who stayed in Pennsylvania USA when she migrated with her parents William and Jane Knopp in about 1857.
