Paul,
I have a similar problem with a great great grandfather that appears in L�neburg. My greatest clue came from finding the Guild records for the town.
If you have not already done so, check to see if there are Guild records for Hannover for the period of time your ancestor lived in Hannover. For me, the Guild records for L�neburg stated when my ancestor registered with the Guild upon arriving in L�neburg as a cabinetmaker and the town he had come from! The Guild records also had recorded his first marriage to the daughter of the master or head cabinet maker in the L�neburg guild. I am not certain if the craft of Urhmacher would be included in the guild, but it would be worth a try.
If the records have not been microfilmed, perhaps you could write or e-mail the Hannover archive to see if such records exist that you could have researched.
For me, this was a fantastic clue to a long-time dead end because my ancestor simply appeared in L�neburg, with no past family records! So, where do you begin looking when that happens!!
Good luck in your search.
If you find good records for the guilds of Hannover and Celle, I would be interested in the information. I am currently working on another family line, but hope to return to the Hannover and Celle area this winter where another branch of my family lived.
I would also be interested in hearing from anyone else that is familiar with guild records and what other information they might contain. The guild records that the LDS church microfilmed for L�neburg were like index cards. I would be interested in knowing if the L�neburg archive would have more detailed records that the cards refer to.
I think that Guild Records can be a valuable resource that is too often ignored or not known about.
