I am aware that Boyd's Marriage Index 1538-1837 is available on FMP for whom I don't have a sub. There are also some random entries on other sites for Essex county which unfortunately do not include the surnames of my interest. I am not aware of these being available on Ancestry - where I do have a sub. I am not averse to using some other sites for a reasonable fee for a one -off search package. What do the forum members suggest?
