William Stringer Stewart was born 10 Sep 1826 and baptised Sep 1826 at St Peter's. Parents Joseph and Ann were of Cunliffe Street, Joseph was a Mariner.
Joseph and Ann are still living in Cunliffe Street in 1841, and with them are children Mary (aged 15), Joseph (aged 10), Elizabeth (aged 3) and Robert (aged 1). GRO Online confirms Ann's maiden name as Stringer on both Elizabeth and Robert's births, and adds a further child, Bancroft, born in 1843.
Joseph was given as aged 40, while Ann was 35.
In the 1851 Census, Ann is living at 34 Cunliffe Street, and appears to keep a small shop. Joseph wasn't there, probably at sea. Elizabeith, Robert and Bancroft are all with her. And also with her was a William Stringer, aged 38, a bricklayer, labelled "Visitor". Ann says she is only 46, which would (if true) mean she was married at age 15!
In 1861, William Stringer is living with a John & Mary Stringer at 4 Cunliffe Street, labelled "Brother-in-Law". He was 48, John was 51. All birthplaces are Liverpool. No sign of Ann, Joseph, Bancroft ...
