Thanks Mary M and Yusser for those tales. I hadn't considered the two surnames having class connotations based on the two pronunciations/spellings. The family I have been interested in were Fargher in the mid-18thC, Faragher in the 1881 census, then Fargher again in the 1891 and 1901 Censuses (although could all be down to enumerators and parish clerks). But come the Great War it was Faragher again and it remained so as far as I know - a family gravestone here in Southport is re Faragher. I notice on the front of the IoMFHS Journals that they use both versions in the tree of Manx surnames.
