Two pieces of documentation finally convinced me that My Paul Garrison, and Mitchell Garrison (2 of the "3 boys from Virginia") were probably brothers. The first evidence, comes from the marriage records for both young men:
Fountain County, Indiana Marriages:
Marriages in Fountain County, Indiana 1826 - 1848
Garrison, Mitchell, Jane Bland, May 14, 1829
Garrison, Paul, Cyla Snook, Jackson Township, Feb. 12, 1832
Frankly, there were hardly any people in Fountain Co., Indiana in 1829 and 1832, so it is rational to suppose that these two Garrisons were probably brothers.
Secondly, there are 2 very old photographs, one of my ancestor, Cassie Garrison, and the other of Mitchell Garrison's son. Although they would have been first cousins, they look like twins. When I saw those 2 photos side by side, I knew that a male line descendant of Mitchell would carry the same Y-DNA as a male line descendant of Paul.
And there is one more interesting tidbit from Fountain Co., Indiana. Here is a quote from a book:
“History of Fountain Countytogether with Historic Notes on the Wabash Valley,” by H. W. Beckwith, pub. Chicago, 1881:
“The first settler established himself in Jackson township at a ‘time out of mind.’ Squire John Bowman came from East Tennessee in 1826, and entered the land across the creek east of Jacksonville, where Z. T. Ward lives.... the next year Richard Williams was settled on the site of Jacksonville. William Guilliams, his son-in-law, was living on the west bank of Mill creek next the town, and on the place occupied at this time by George W. Brown; and Isaac Crowder had a cabin on the farther side of the creek south of the town, where Antoine Weaver is living. This same year (1827) John Hybarger, who had left Tennessee the year before, had stopped at Russellville, arrived and entered the land where his youngest son, John, now has his house. Thomas Allen was at this time located on the county line between Park and Fountain, on the farm now owned by Henry L. Roach; and Jonathan Cunningham joined him on the east. These two men we from Virginia. WILLIAM SNOOK and JOSHUA BLAND, from Ohio, had their homes on Sec. 16; Ephraim Dell, a young man, was here; George Low has come; and Cuthbert Harrison was living north of the present Jacksonville. JAMES GARRISON and Ewlet came early also, and made homes near and north of Elijah Clore’s. Armstrong settled where Henry Williams lives. None of the GARRISONS, Ewlets and Armstrongs remain.Michael Hutts, Ezekiel Nelson, William Murphy and Isaac Gooding were early settlers. A little later William Hinton came, and the Myerses, Fines, Shulers, Livengoods, Grimeses, Sowers, Scotts, Clarks, Kellers, Jacon Clinard, John McSpadden, and George McLain. The country was settled rapidly after the first four or five years. Nearly the entire immigration for some twelve years at first was from North Carolina and Tennessee. A few came from Virginia, still fewer came from Kentucky, and perhaps two or three were here to represent Ohio.”
So now we need to track down information on that James Garrison who was in Jackson Township, Fountain Co., Indiana in it's earliest days. Was he the father of Paul and Mitchell Garrison? Notice that the father-in-laws of both of the boys are named in the above book as being among the first settlers of Jackson Township, Fountain Co., Indiana.
How fun and exciting!!
