Moneth 11 day 13 Joseph son to John Mayo [baptized].
[Note: In old-styles dates, the eleventh month is January. For comparison to the modern calendar, it corresponds to the following year. More info may be found here.]
[Note: Source:Mayo, Chester Garst. John Mayo of Roxbury, Massachusetts, 1630-1688, p. 34, says the baptism date is "13 December (Nov.) 1666" which is impossible, but the author apparently assumes birth in Jan 1666 meant 1665/66. The reference to November appears to confirm a complete misinterpretation of the dates.]

MAYO, Joseph, Capt., [died] Mar. 5, 1747, a. 82 y. GR1
[Note: according to the inscription, the gravestone says aged 82 years (i.e., not in 82nd year). Assuming the death date is 5 Mar 1747/48, as would be expected for an old-style date, this corresponds to a birth after 5 Mar 1665/66 and before 5 Mar 1666/67.]
