Hi Sarah & Andy
Thanks for your input. It clearly states 'Son and Inmate' on both death certificates and you prompted my memory, Sarah, and I recall seeing the term 'inmate' on Poor House lists.
I have now checked all the census results for 1861, 1871, 1881, 1891 and 1901 and find that the children of this family didn't marry but remained together. After the mother has died in 1884, there are in 1891, 5 of these children all between 31 and 42 still living with their father. It would appear, Andy, that your reply is spot on and it just means that he was still living with the others. Many thanks, PWN
