Hi
I use the site all of the time, and the people can be quite helpful. However I am not real good either.
I have done research in Suffolk, and although I am not sure, I think they keep the records in Bury St. Edmunds for a lot of the surrounding areas. It is like a registration District I think. So maybe Jane was christened in another area close by. There are hundreds of parishes in Suffolk, and only a few km apart.
The film. Have you used the LDS site. I think it is:
www.familysearch.org - or ask google for the LDS site in UK. When you get the site, you click on Library catalogue, and click on place search and type in the place you want, and then follow the prompts. However Bury St. Edmunds has a lot of films I think. You could ask one of the family history groups there on the net. I think there are help sites on this site. Ric is the moderator, try and find him and ask him.
Have you bought Jane and Johns marriage certificate - it might tell you her parents.
I am going overseas on Monday, so I hope you can find someone to help you.
