Hi Pat, I've concentrated my past research on the UK origins of the Mumbys. Most were from Lincolnshire. However, I'm just starting to paste together the Ontario based Mumbys, all of whom I'm sure have their roots in Lincolnshire, and I'm pretty sure there are connections with my family branch. Email me at firstname.lastname@example.org, and if you have GEDCOM files that you could send me, that would be great. I will then add them to the Mumby genealogical database that I have set up on the web. As well, there is a birth, marriage and death database for locations in north Linco;lnshire. Regards, Dennis.
