Thanks for the info. I will tell the Gumm ancestors I know to check out this site.
About "Gum", "Gumm" - The first verifiable trace goes back to Norton Gum in Knoxville 1793. Judy Garland's father, Frank, changed the spelling about 1906 and many of the family followed suit. Before that it was always spelled "Gum" by them.
I worked with other relatives to unravel the mystery as some likes were lost and there is no official record - ie lost marriage licenses, deat cert non-existence in this part of the country many years, burials wherever people went and this part of the family not having much money to buy property. A rare 1866 letter was finally found (which is in my book) verifying the information that three of us had pieced together. So I have the line back to 1793.
Now, if anyone is interested, it will be just be a matter of proving how this Norton Gum relates to the rest of the family.
PS Some place online have suggested that "Gum" came from Germany, but I was glad for the posts on this site, confirming what we already thought - that they were from England.
