Only YOU can decide whether its worth the bother.
FWIW I have two families in a tiny Warks village, parents Richard & Hannah, that I'm trying toQ disentangle. If the vicar had put both Hannahs' maiden names it would have made life simpler.
Similarly, trying to find my gt x 3 Norfolk grandmother, surname Seals. There are a few Seals in the register but none around the right time frame to be immediate family. But there are also Scarls, Searles, Sales etc. I've just recorded all the instances and drawn trees where I can for the separate families in the hope that further info may help me include or eliminate them.
Quite often, even if the surname is spelt consistently, you find yourself faced with several John Massinghams who marry Marys and can't sort out which is whom!
