I'm looking for any "scholarly" info source that actually says that Malcolm Beg DRUMMOND, born circa 1210 was married to Ada of LENNOX, aka Ada of MALDWIN, etc., the daughter of Maldwin, 3rd Earl of LENNOX. I know a lot of people repeat that info, but has it ever really been verified? This Ada has some very well known individuals in her ancestry, but before I waste time on that angle, I want to make sure that Ada was actually married to the above DRUMMOND and is an actual ancestor of the Drummonds. I have noticed a tendency for people to put down things they read off the internet without verifying it, which has already led me astray several times. Does anyone know of an actual source, a record, a learned authority of some type that says that such a marriage actually occurred? I don't mean someone's ancestry from the internet which may have been simply copied from something they read at another site. I have been, for the last year, working on the angle that the Drummonds were actually descended from Andras or Andrew I, King of Hungary and his wife, Anastasia Yaroslavna of Kiev. Yes, people write that down, even official sites for the Drummonds give variations of that info, but there are a lot of sources that indicate that many of the early Drummonds "embellished" their ancestry and were in no way descended from the King of Hungary, but were descended from a chamberlain (Malcolm Beg DRUMMOND) in the service of the Earl of LENNOX. Does anyone out there have any scholarly sources, rather than hearsay, about the actual history of the Drummonds, in particular this Ada of LENNOX (or, for that matter, who Malcolm Begg was actually descended from)? She is a key figure with ties to lots of well-known figures of the past? I am not trying to insult anyone, I'm just trying to get the "straight skinny." While my surname is German, I have Drummonds in my ancestry and a lot of other Scots (e.g., MacKenzies, Creightons, Nicolls, Moffatts, Gillies, MacKays, etc., etc.), as well, in case anyone is wondering. Thank you!
