I have two microfilms from the LDS Church/Family History Center on Bristol Vital Records if there is something anyone needs to have looked up. The dates on film are:
Marriages - 1820-1841
Births & Deaths - 1791-1947
Marriages 1841- 1854
Births, Deaths, Marriages - 1847-1871
Births - 1871-1892
Births - 1892-1897
Marriages & Deaths - 1871-1898
Births, Marriages, Deaths - 1898-1903
These are not the actual certificates microfilmed, but rather the vital registry books. They do have a lot of helpful information though.
I have looked quickly through both these films and found a lot of valuable information. I go to the Family History Center at least once a week and will be reviewing these films again more thoroughly, so if you need a look up of an event that happened during any of the dates above, please email me.
This is for free, I am just trying to be helpful with the materials I have as others have been helpful in my searches.
