There are several Bopp lines - I don't know of any book about any of them. My husband's family had a little genealogy booklet at a 1938 reunion. But I need more info to find out if this is your line.
I have some general info at this link - about some different Bopp lines but this is not comprehensive:http://freepages.genealogy.rootsweb.com/~gkbopp/BOPP
Are you new to genealogical research? If so, tell me the name of your Bopp grandfather or greatgrandfather - a Bopp relative who was alive 1930 or earlier. Need his full name and where he lived (City, State, etc.). I might be able to help you a little to get started.
Also - if you are young (under 18) discuss this with your parents. I've had a couple of cases in which young people asked for info and the parents were very upset, worried about stalkers and things like that.
If you don't want to put any info on this public list, you can email me privately email@example.com
