Although I donÕt have answer to your question, I do have an observation, two possible solutions, and an offer of help:
Observation: If Benjamin Lord (b.1694) was the father of Joseph (b.1763), then Benjamin was about 69 at the time. Unusual, but not impossible. But if Ann Taylor was 15 - 20 when she married Benjamin in 1720, then she was 58 - 63 when Joseph was born. IÕd conclude she wasnÕt his mother.
Possible solutions: 1) Ann died prior to 1763, Benjamin remarried, and his new wife was JosephÕs mother. 2) ThereÕs a missing generation.
IÕd propose a guess, based on the fact that Lucy Adgate (b.1731 in Norwich) married Joseph Lord:
* Benjamin Lord married Ann Taylor, and they had a son Joseph, born ca 1730.
* Joseph (b.1730) married Lucy Adgate and they had a son Joseph (b. 1763).
* Joseph (b.1763) married Lucy Abel and they had a son, William Adgate Lord, the middle name coming from his grandmother.
An offer of help: I hope to go to the Rochester Public Library in the next week or two: they have a copy of the Norwich Vital Records (and some other interesting stuff) and IÕll see what I can find.
In the meanwhile, IÕd be very interested in your opinions on the above.
