Does anybody know anything about this lady's forebears. She was born in Pimlico, London in 1821 and had an illegitimate son, Francis in 1841. In the 1851 and 61 census they were going under the surname of Cranstoun. He reverted to the name Burchett when he maried in 1864. Her death in 1870 was recorded as Cranstoun Ann Burchett. Any help would be appreciated, she is doing my head in !!!
