Hi
Given the information you will have to make a note of the names you are looking for in the Huddersfield & Upper Agbrigg registers they could be in either.
Freebmd is easy and I find very user friendly. Go to search then you come to the next page. Then just click on the one you want, (birth marriage or death) then just enter the surname in the box and then the first name. After you have done you enter the year range you want, I usually keep it to 5 or 10 year spans. If you have a common name their is a section that allows you to narrow the search to a selected area.
Regards
John
