James died aged just 34.

Emma was the widow of James Tandy when she married Richard.

She can be seen in the 1881 census living at 7 Court 2 House, Birmingham, Warwickshire. She was already a widow and had 4 children at that time. It wasn't until 1890, some 9 years later that she married Richard Knibbs.

In 1881, she also had what were quite possibly three of her siblings living with her as lodgers.
They were Samuel Hall (27) and unemployed, Thomas Hall (22) a Saw Tooth Setter and Ann Hall (20) a Spoon Polisher. There was also Lilly Hall aged just one month and listed as "daughter" on the census.
