Thanks Gilby, it's beginning to make a bit more sense now. George seems to have been the eldest child of John and Susannah Bell. William Bell died in 1845, when he would have been aged about 19. Unsure why George was named as the guardian of the children as father, John, did not die until 1845, unless John was incapacitated.
I believe my Conway Bell emigrated to USA and died 23/02/1905, aged 75 years, 3 months and 26 days, (should be 74 years). Conway is recorded as single. Place of death recorded both as Cleveland, Cuyahoga, Ohio, USA and Pittsburgh City, Pennsylvania. COD was Uremic Poisoning. Was buried 24/02/1905 at Woodland Cemetery in Cleveland, Cuyahoga County, Ohio. Parents recorded as James, (should be John), and Susannah Bell.
