I have several Pipes in my Dudgeon family that are from Knox Couny, Ohio. I have a William Dudgeon b. 3/20/1861 d. 12/13/1928 he was married to Emma M. PIPES b. 1866 d. 1936 both are buried in Union Grove Cemetery.Then Persus J. Dudgeon b. 1857 d. 1926 married to Alice PIPES b. 1891 d. 1928. Do any of these names match any of yours? Thank You!
