There is a Matthias S Wallis, proposed address in England (don't know where I got born from) Longrock? Penzance Cornwall, he is aged 35, on an incoming passenger list in 1922, ship Homeric, also a Mabel aged 33 a Housewife. I think it says he is a Butcher but I am not sure. Previous residence USA.TressleADDING - it does say intended place of future residence is England
I have found the same couple going back to USA in 1929 so probably not your man if he died in NSW, his is a Butler not a Butcher. Last address was Penzance Cornwall. Going to New York on the BERENGARIA.Tressle
