Rob,
In this deed, Emma Radnich conveys whatever she owns in the tract, surface, minerals, royalties, etc., but SAVES AND EXCEPTS a 1/32 non-participating royalty interest (NPRI), the 1/32 being 1/4 of the "ordinary" (at the time) 1/8 lease royalty. I am positive of that. It's non-participating because it is a royalty interest only, not a mineral interest, and therefore is not entitled to sign a lease or receive bonus, shut-in payments, or delay rentals.
"They" say the words in parentheses are the "forever granted royalty," you say it is the "current example not the limit of any royalty forever in the future." You are both wrong. First of all, nothing is granted in these words, it is RESERVED, to the Seller, and her heirs and assigns. Secondly, the words in parentheses define the word "royalty" right before the first parenthesis to be what was then "ordinary," 1/8. So the words BEFORE the parentheses, when combined with the words INSIDE the parentheses, say that what is RESERVED...FOREVER...is 1/4 of 1/8, or 1/32 forever.
The existence of this NPRI could explain why you are getting "two different royalty fractions," one fraction for the 1/32 NPRI and another fraction for your pro-rated share of royalties payable under the lease, less your pro-rated share of the NPRI. In other words, if you somehow now own the 1/32 NPRI that Emma Radnich kept in this deed, and you somehow also now own a mineral interest under this same tract, that would explain why you have "two different royalty fractions." These two fractions are not in conflict, it's not like you can have only one and not the other, they are complementary, meaning that you get them both!
What I am not positive about is the phraseology at the bottom of the page, it appears to me that the Seller, Emma Radnich, is also putting the Buyer, Mr. Lane, on notice that either she or an owner previous to her in the chain of title conveyed 1/4 of the minerals to somebody else. So Mr. Lane probably got 3/4 of the minerals, somebody else had the last 1/4 of the minerals, and Mrs. Radnich had the 1/32 NPRI. The royalties payable under the NPRI are reduced from whoever owns the minerals on that same tract, so if you own a mineral interest AND the NPRI, then the royalties payable to you as the mineral owner will be reduced slightly to help pay you as the NPRI owner for THOSE royalties. Confusing, but maybe it helps.
