Hi Suffolkmawther,
Many thanks for the welcome! I haven't checked the Walsham PR's yet. I'm at a small disadvantage (perhaps) being in Australia, and have yet to tap into a source here that holds MF copies of some of these smaller parishes. I approached the Church of Latter Day Saints, who had some of the possible ones listed, but a phonecall showed that these weren't actually available.
I've come across the James Rosier in the 1844 directory too, and originally thought that was my man. But later research showed he was in Bedford by this date, and the the trade didn't seem to fit with the closer slide from watchmaking skills into gunsmithing.
I wasn't aware Walsham was rather active. I certainly got the impression from the directories Langham was rather on the small side of things. Elizabeth's father was one of the early founders of Henry Watson's Potteries, still in existence today (

It's sounding like Walsham might be my best hunting ground. I guess I should ask - as we're here in requests - would anyone be in a position to check this for me? How many churches are there in Walsham? Don't want to send anyone on a wild goose chase.
