It has been suggested that this Freelove may have been Freelove Tillinghast. However, Wayne G. Tillinghast in his book "The Tillinghasts in America" disputes that, offering evidence that William's wife could not have been Freelove Tillinghast -- at least not the daughter of Joseph Tillinghast. See page 150, where he notes that William & Freelove Allen were admitted to membership in the Second Baptist Church at Newport on 4 March 1729.
She also is identified as Freelove Tillinghast in the RI Genealogical Register Vol. 6 No. 4 p. 241, "Descendants of John Maccoone." The compiler of this article did not note his source, which may have been DeVere Allen's work on the Allens of Prudence Island.
