Progress, indeed. finnleikr was an earl in Scotland around 1000
(finnleikr skotaiarl); the others present no problems. Here are some
Modern Icelandic constructions:
finnfríður : finndís : finnbjörg
We also have a post-reformation *finnbergr (finnberg 1740-50 in
south-east Norway). Hmmm. The last 4 all look good and ancient, but
we lack pre-reformation sources for them. I'll let the readers look
more closely at these, while listing the pre-reformation sources:
13 plus one reconstruction: *finnelfr - mascs. in -alfr yield fems.
in -e,lfr in the other categories. *finnbiorg would be likely, but I
have no *finnsteinn, even though there is a finnbiorn, and *-laugr
would be logical, but mascs. are so much rarer against feminines in -
laug that I won't take the chance. So, 13 plus 1 reconstruction.
