Arthur Edward, who married Bertha, had the following siblings:
Walter John, born 1872 Chacombe, Northampton - finally placed that one Thomas A., born 1874 - don't know where. Albert L., born 1876 - Williamscote, Oxford. Francis W., born 1879 Chacombe, Northampton.
Their father John Campion was married to a Mary B. (surname unknown).They were both born in Oxford.
I suspect that Mary Elizabeth Campion could be the eldest of their children but I have not managed to verify this as yet.
I believe Walter John married Margaret E. (surname unknown) and they had the following children
Walter J Herbert A Annie E Frank
They were all born in Wolverhampton between 1893 and 1901.
