George's wife, Harriot Spragg, had died 27 October 1839 at Paddington, Middlesex (Greater London), England.
They were the parents of 3 known daughters: Mary Ann, Emma and Harriot (#19366844); the latter married Henry Saul Brooks on 22 December 1851 at London, England. [She and Henry immigrated from England to St. Louis, Missouri and remained there and in Pawnee, Riser County, Nebraska until about 1860, when they came to the Great Salt lake Valley. They settled at Provo for a time and then at Lake Point, Utah County.]
George had been traveling in a wagon train with Mormon immigrants in the Jacob Gates Company of 1853. His age was listed on the wagon roster as "51". They left Keokuk, Iowa on June 3rd.
Several Trail Journals record his death at "Rattle Snake Creek, Nebraska" - the most descriptive being that of James Farmer: "July 26th. Fine morning and the cattle all safe[.] started about 8 and at 9 Bro. George Horsefall [Horsfall] died, he had been ill some weeks and was unable to stand the fatigue of the journey[.] belonged to Paddington Branch London Confc [Conference.] aged 45[.] he was interred about 9 miles from our last camp ground on the left hand side[.] about 2 miles from there stood 3 trees in a row about ¼ of a mile from each other and close by the grave is a beautiful running water."
This location was described by others as being about 180 miles east of Winter Quarters. The Rattle Snake Creek runs (across Nebraska) north to southeast from Sioux City to Omaha; where it intersects near Wood River would be the location of the Mormon Trail crossing spoke of.
Another Trail Journal states that they erected a "grave tablet", which would probably been fashioned of wood.
