That looks like Tyler to me. I realize the "e" looks like an "o" to modern eyes, but at that time English scribes wrote the "e" a bit differently. See the end of the word "single" describing the groom, for example, or see the "e" in "Cooper" (groom in the marriage two lines above yours).
I do not know the meaning of the double dates for the marriages, but doubt that it has to do with the ages of the brides and instead suspect it has something to do with when banns for the marriage were issued.
