Re: JOHN Trewartha married Bessie GERRANS 1888 Sonora, Tuolumne, California
John Trewartha's parents were Samuel Trewartha and Elizabeth Ann Oliver which were also the parents of my greatgrandmother Mary Godfrey Trewartha that married John Augustus Powning.
Hope that answers your question. I have nothing on Bessie Gerrans other than she and John had a Gertrude and Ethel Trewartha. Bessie married a J P Gallagher on Feb 2 1902.
