I found your Walks buriel information at the Library today. Both Martin & Elizabeth are buried in the Friedberg Moravian Church Cemetery here in Davidson County, NC. Its only about 10 miles from my home. I'll try and get over there tomorrow or Monday and get photos if possible. The information in the book says that Martin Walk was born Apr 2, 1737 and died Nov. 18, 1791. Elisabeth Tiscus Walk doesn't have a birthdate listed but her age is given as 75 y with a date of death Nov. 10, 1825. "Pennsylvania" is shown under her name in the book. I also found a Joseph Walk b. in Davidson County on Dec. 16, 1773 and died July 28,1839 and a Louisa C. Walk Butner b. Dec 8, 1809 and died Apr 4, 1865. Maybe these 2 are yours also.

I'll let you know what I find at the cemetery.
