Hi Kath,
I think that the Birth of Elizabeth TAYLOR 9th Feb 1788-Averham - daughter of Thomas & Mary TAYLOR is, given all the facts, credible.
The marriage of Charles HOLT to Elizabeth TAYLOR 1st Oct 1805 Spridlington, Lincolnshire would on the face of it, look a little shaky.
The Original marriage certificate (available on Find My Past) shows that the parish given for both Charles and Elizabeth is GLENTHAM which is just north of Spridligton.
However, given that Glentham is only about 45 Miles away from South Emshall and 35 Miles from Averham, it would seem highly likely that Charles and Elizabeth had independently moved to the Glentham area to find work. We shall never know for certain but I feel comfortable with the assumption. knowing that our ancestors did move about more than we imagine.
Best wishes
John
