Nathaniel Monday son of George was baptized as an "adult" at St. Paul's Episcopal Church in Wickford on 18 July 1819. It does not say how old he was. The church records also mention Captain George Monday and his wife Ann (baptized 1821), and daughters Elizabeth, Hannah, and Phebe, all baptized 2 Jan 1825. Ludowick and Daniel Updike were associated with this church in 1809.
George Munday and family are in the 1820 census at North Kingstown, RI. The family has 4 individuals: one male age 26-44, one female age 26-44, one male child under age 10, and one female child under age 10.
In 1840, George Munday and family are in Fall River, MA.
In the 1850 Census, they are still in Fall River: George Munday 60 (Nova Scotia?), Anna 59 RI, Hannah B. 27 RI, Phebe T. 26 RI, Lucy P. 21 RI; and George W. Whitaker 10 MA. George Munday is a clerk. His birthplace is not correct -- see his birth record in RI and death record in MA.
The death record at Fall River says he died at age 65 of lung fever. It gives his birthplace as RI, and names his parents as Nathaniel and Elizabeth, which agrees with his birth record.
