I have traced my husband's family back ti Bradford, Yorkshire, Eng. There are so many Firths there with similar names, it's nearly impossible to separate them all. Has anyone worked on the families there? I may have to do it, since I live near the Family History Library in SLC. I was told by an English women I met once, that Firth was "A good old Yorkshire name", so I guess that may be where most of the Firths come from. If you want to email me directly, my address is dragonshelver@hotmail.com
