I'm looking for the demise of Robert Birkbeck who legged it from Grinton in Yorkshire away from the Lead mines. He became a Coal Miner and was last seen 1871 census at Shildon born 1826. Wife Elizabeth nee Dent. Six children the last Margaret born 1870 Eldon. Is anyone else shaking this tree? please. Thank you Josi Birkbeck
