Hi Robert. Joseph was my GG grandfather too, so I guess that makes us very distant cousins. Joseph & matilda had a son called Percy Dene Isherwood, who later changed his name to George Williams (we're not sure why). Percy's daughter Ethel was my Nan.
I have loads of information on the family so would love to share info. I am aware that Albert emigrated but not really anyhting more - I think I have his emigration record and a directory listing from the 1930s. I also have a record for another daughter Dora Isherwood (b1930 Sydeney, d 1998 Harbord)
I have traced Joseph back 2 more genrations and Matilda 3 more. They lived in Liverpool & Manchester in the UK.
Please email me if you would like more details email@example.com
Great to find another cousin.
All the best, Vicky
