Albert I von Dagsburg - Is Albert's father Hugo IX or not.

Alex, what is the different between speculative and unsupported in this case, it's clear that there is no recording that Albert I was the father of Albert II, he could actually have been a grandfather, but were they related, more than likely since the County of Moha was at that time an allod, in fact, the landowner had the same right like a prince, and as such, Moha goes from father to son.

To me when the notes for Albert says "Wrong Father.... this profile is incorrect too... " a red flag goes up. If it said speculative and unsupported then you can say the lineage may or may not be correct. A lot is posted here from "MEDIEVAL LANDS" which says 2 children not 3. I mentioned in one post that I had seen several that said parents are not known, but they have parents listed and was told to flag it with a discussion, I think this would fall under that statement.

Eddie, you can't rely on DIY links on the web, but there is another problem here.

Mathilde Albertsdtr von Egisheim

Mathilde von Moha

Can you see what?

I try not to rely on the DIY links. I know that the LDS site just puts out what is given. Rootsweb shows who loaded their tree and you can pick one and hope its right. Since this site says it is a one world tree and they have people to take care of it you would hope it would be better. I think that you have two Mathilde's (looking at the parents names) but their birth dates may be wrong along with Hugo's but I'm not seeing what you are pointing at. It list Hugo VI being born before 1074 and death in 1049 with his sons Gerold being born 954-1074, I think this could be a little better.
