I'm not sure what the 'm' stands for, or the possible name after it, in the second baptism, but as you're interested in the first baptism of Robert, this won't be of significance.
It may well be 'in', (this scribe doesn't dot any of his 'i's, which makes in more difficult to distinguish the letter from other letters), in which case the words may be a place name.
It would be useful to see a little more of the page, or the register, to see if this sort of entry occurs at other times, which might give some clues to what it means.
