I have found a William Briggs born about 1862 in Houghton le Spring. He was a coal mine hewer married Jane (don't know when)Jane was born approx 1856 in Shotton. William had some brothers and sisters the only ones I have found so far are Ellen b. 1865 Shotton (married Martin Wheatman) and Ralph b. 1844-45 Cassop.
William's parents are also William b. 1820 d. between 1871-1881 and Jane born in Spittal in 1823.
Ooh I have a Jane Henderson Briggs born in Sept 1884 to William and Jane.
This sounds very promising to me. What do you think?
