So today I was looking over the FFC maps of Zvenzens Freehold and its really amazing how much detail is given on them. The rooms are all detailed and there are rooms on the second floor that have names attached to them. One of them says "Mello" and I suppose that to be the well known hobbit, but other rooms are labeled:

Tuahm
Sgreg
Bicarill

Who are these people? Svenson's family?

Except for Mello, those names are not familiar to me, either. Svenny's closest companions at the time the Freehold was built were Mello (as noted), The Blue Rider and Bishop Carr. They actually helped with the project. Jim Barber, Stephan Rocheford and Dave Belfry were also close companions at the time. Later, Martin Noetzel, Bob Meyers, Scott Belfry and the Snider brothers were also among Svenny's companions. So, the rooms could have been intended for any of them. That level doesn't look all that familiar to me at this point. I did the floor plans when I was taking an architectural drafting course in the Spring of 1972.

Yes, my floor plans were redone before FFC came out.
