the look up service will only look up a specific file but I only have two surnames that may be there , is there any way to access this information ?

The FamilySearch catalog entry is https://www.familysearch.org/search/catalog/398186 and there are 35 different microfilms which appear to be arranged alphabetically.

You can currently access these records at a FamilySearch Affiliate Library, although access at Family History Centres is not possible for the next few months.

You could also try the Family History Library Look up service https://www.familysearch.org/family-history-library/family-history-library-records-look-up-service
