Does anyone have any information about La Mothes still living in the IOM or elsewhere?

John Corlet La Mothe (1838-1898) author of Family La Mothe on the IOM website was my great, great grandfather so I have a full tree going back to Dominique La Mothe's grandfather Jean in France as well as information about all of those alive at the time that document was written (1895) but I don't know much of what happened to the 20th Century La Mothes other than our own line (in Australia).
Thanks,
Pat
