Michelle, The LDS church has indexes for Antrim, and because it is in NI, they have the actual certificates as well (depending on the years). I suggest your go to www.familysearch.org to find the LDS Family History Center nearest to you. Click the Library tab,then at the bottom of the page there is a link to find a nearly center. Here is the exact URL: http://www.familysearch.org/Eng/Library/FHC/frameset_fhc.asp?PAGE=library_fhc_find.asp The people at the FHC will be very helpful to you in starting and continuing your search. Searching with films they have on-hand is free, and ordering additional films is quite inexpensive. it would be VERY helpful to know WHERE in the county they lived. If I can be of further assistance, please let me know. Andy Airriess Researching McCormick and Boyd in the Belfast area
