A good start is to thoroughly explore the GENUKI site, particularly the sections "Getting Started in Genealogy and Family History" and "Researching From Abroad". Your local library probably has a book or two on UK family history research.
For further help and information about MASON in Yorkshire, post on the Yorkshire board. Include as much information as you have (first names, dates, etc.) to enable someone to help you. YORKSGEN is the free RootsWeb mailing list for Yorkshire and an excellent source of help. Subscription instructions and list info can be found at
http://lists.rootsweb.ancestry.com/index/intl/ENG/YORKSGEN.h... Wouldn't hurt to join the MASON mailing list as well. There's one specifically for MASON in England. See

Note: Be sure that any post on the boards is relevant to the board on which you post. If you post on a location board, reference to that location must be made within your subject line/post. See Board FAQ for more info about posting on the boards.
