Hi avm, thanks for that info. Have got family now in 1881 census.
Have also found in 1891 census son of George and Sarah - John born 1878.
Found this entry in 1881 census;
John Cox Head 51 b - warmington Northhamptonshire
Mary Hannah Cox Wife 50 b - lutton, Northhamptonshire
John Thomas Cox Son 16 b - lutton, Huntingdon
Joseph G Oliver Nephew 15 b - lutton, Huntingdon
John Edward Cox Grandson - 2 - b - lutton, Northamptonshire.
Can I assume that John & Mary are George b1855 parents and that they were minding John on the night? many thanks again - cheryl
