Church st and College St in Ramsey were pulled down some 30 years ago .
The mormons filmed everything in the Rolls Office in 1948/9 thus the Isle of man is very well covered by these films - see www.manxnotebook.com/famhist/genealgy/ldsfilms.htm for a partial listing.
Virtually all the burial registers and the MIs of all the Island graveyards have been transcribed/recorded - see Brian Lawson's site for an index to the Burial regs as well as other material based on the Mormon films - Brian has also index all censuses.
The newspapers on microfilm are one major source not available on Mormon microfilm, - there are of course many other historical records in the Manx Museum library but most of these are peripheral to family history research
