I can give you some information on Peter Yurk.
Peter married Emma Warnash and moved to Lexington Texas. He was born Dec. 2, 1864 and died May 2, 1934. His grave is located in Lexington. I'm not sure on the number of children he had but one of them is Richard Carl Yurk who married Adelheid Anna Yurk. They had four children and five grandchildren.
