Looking for info on my ggggrandparents.Margaret ABBOTT married James CLARK (dates unknown).Their daughter was Rachel CLARK b. 8/24/1839 in Saxton PA and d. 12/1/1921 in Brandywine OH.In 1857 Rachel married William SCHELL b. 8/24/1832 in Huntington Co. (now Blair Co.) PA. and d. 1/6/1912 in Brandywine OH.These Clarks were somehow related to William Clark of Lewis and Clark Expedition. Would like to find out more about this Abbott line, as well as the Clark connection. Thank you!
