This message might surprise you, but I think you'll find it interesting. Our 6x great-grandmother, Elizabeth Brownlee Guthrie, was rescued by Captain Robert Lottridge. (Source: A Captive's Tale, written by Anna L. Warren of the Westmoreland County Historical Society in Westmoreland, PA).
She was captured by the Indians in a raid on Hannastown, PA. She had gotten ill and the Indians intended to torture & kill her, but Capt. Lottridge intervened and convinced them to take her to Niagara in exchange for rum.
Apparently, his family were in the hands of the colonials. His wife and children were listed as prisoners. (Haldimand Papers, Public Archives of Canada Microcopy A-682:424)
Also, "Return of the Persons under the description of Loyalists Specifying the Number, Age, Sexes and Number of Rations Drawn by FAmalys in the Indian Department, Niagara, 1st December 1783" - Robert Lottridge, age 34; Mary Lottridge, age 30; John Lottridge, age 13; Robert Lottridge, age 11.
Ms. Warren indicates that the names Mary, John and Robert are bracketed with the notation "In the colonies." Ibid., 375. She thinks his 2 daughters might have died in captivity.
I hope this helps! I am interested in as much information on Captain Lottridge as possible as well. Hoping to find a descendant that has information about the captives. (Elizabeth Guthrie survived, remarried (her husband had been killed) and have 10 children. My husband is descended from one of them. So hundreds of Guthrie descendants have Capt. Lottridge to thank for helping her...
