Thank you for the input on William Brazelton II.From other information I have seen, I did not think he went to Vermilion County until the 1830's.Now I see he was there somewhat earlier and probably was responsible for convincing others in the New Market area of Jefferson Co., TN to join him.
Based on child births and similar data I estimate that Israel Patton, my ggg-grandfather, left New Market in the Spring of 1827 headed for Vermilion Co., IL.He took along his wife, Hannah Mills Patton and two young children, Samuel and Mary Ann.Once arriving in Vermilion Co., another son William was born in Georgetown in November, 1827.
Although Patton was not a Quaker, his wife Hannah was although she was dismissed for the breach in unity.She eventually was allowed to the Monthly Meetings at Georgetown.The MM at Ridge Farm, where Patton farmed, burned down sometime in the 1840's.It was adjacent to the Pilot Grove Cemetery where both Israel and Hannah Patton are buried.
Evidently a large group of persons made the migration to Vermilion County from Jefferson County, TN including well known families like the Frasiers and Brazelton's and a number of Mills related families including the Millikans.
To answer your question, Col. Brazelton was William Brazelton(1792-1877), a son of William II (1766-1863)who moved to Vermilion County.This is in addition to the son Jacob you mentioned.The military title came from his being a battalion leader of Tennessee Calvary during the Civil War.He lived his whole life around New Market, Jefferson Co. and once owned sizable holdings of land.
