My grandparents are BENJAMIN burton BRIGGS B 22.04.1892 and Ella Mae Guiggey b 17.09.1898. They had 4 children their son Edward was my father.Their parents were George William Briggs b 05.12.1843 and Margaret Ann White b 04.08.1852.George's parents were John Briggs b 1818c and Catherine White b 1819c. birth years taken from 1851 census.I have paid a researcher in Fredericton but he was unable to find either their marriage or birth records.I note that you have put John's father as Ephraim Briggs and Abiel as grandfather.I have seen other people's trees who make the same connection butI have been unable to find any records confirming this. Can you please tell me what records you have to make this link? There was another George Briggs b in the 1840s in Maine.
