Replying to Bob Henderson's offer of info. on London Taverners. Hope that you are still monitoring the forum. I also have an ancestor Joseph Taverner of the parish of St. Stephens Coleman St. London who married Elizabeth Lewin of Broxborne,Herts. on Feb 1, 1752. (So he doesn't seem to be the same one as yours.)After marriage they may have lived in Moorgate as I have found an apprenticeship record dated 23 Nov. 1781 to the Musician's Company for a Joseph Lewin Taverner, son of Joseph Taverner, cloth merchant of Moorgate.Actually the name Lewin stayed in my family right down to my father's elder brother. I am trying to get back beyond the 1752 marriage. I do have the line confirmed I think from there to the present day.
