Hi Thanks for last reply to my query. I had made a mistake as to Obadiah's mother's name on the 1881 census. Her name on this census is Jane, but I find her named Jenty on the 1871 census.
Re the baptism of Genty/Jenty Gray in 1835. I have accessed this through Family search. This states her baptismal date as
29 Nov 1835
BUTTERWICK HOLLAND,LINCOLN,ENGLAND. Parents named here are Father: Dezrey Gray and Eliza Herring. I found the family on the 1851 Cenus as Orsary Gray and Eliza. Jane (Jenty) and her brother Samuel are also on this census. Samuel is the one who apparently married Ellen Dianna Gray and their child Ada (h) married her cousin Obadiah, Jenty's son. All very confusing. Where do Edward and Rosa Lovell fit in?
