Orr, Robert a Presbyterian minister, who flourished in this country during the colonial period, was either a native of Scotland or Ireland, probably of the latter country. He came to America in 1715, and accepted in that year a call to Maidenhead and Hopewell, and thus became a member of the first American presbytery (organized in 1705 or 1706 at what is now supposed to be Freehold, N. J.). Orr died about the year 1725. See Gillett, Hist. of the Presb. Ch. 1:29, 34.
