NOTES (JDH 9/26/2003): This John Walker is very likely a son of our ancestor Charles Walker, and younger brother (by 16 years) of our ancestor William Walker. This sketch gives Jane Short as the name of Charles' wife.
This sketch was sent by Jay Kimmel who had these comments: William and John Walker were both sons of a Charles Walker. Each Charles was from Virginia and settled in Chillicothe, Ross County, Ohio. Both William and John were born in Virginia before 1800, both were married in Ross County Ohio in the early 1800's, and both came to Fayette County about the same time.
Added by JDH: About 1821, both William and John settled at first about a mile from each other in Jennings Township, Fayette County. See further comments below the biographical sketch.

JOHN WALKER was born in Virginia, December 26, 1793. He was the son of Charles and Jane (Short) Walker. When quite young he removed with his father to Ross County, Ohio. Here he grew to manhood, and at the age of twenty-two, he married Eliza R. Jefferson, a young lady of English family, eighteen years of age. In 1818, John removed with his wife and two small children, Lewis R. and Kittie I., to Fayette County. He settled at the place where Lyon's Station now is, and entered nearly a section of land in Rush County, and on to which he removed in 1823. While in Fayette County, John W. and William L. were born. His first cabin was erected near the spot on which now stands the commodious residence of his grandson, Commissioner William L. Walker. Here were born James Q. and Edward T. In 1828, on August 4th, while John Walker was in Ohio on business affairs, his wife died, and ere the return of the pioneer to his family, the companion and mother of his children had passed away. The wife had been dead two weeks before he returned. On January 8, 1829, he married Rachel Russel, a native of Ohio, born September 27, 1808. The following are the children of this union: Benjamin R., Eliza J., Henry F., Rachel A., Lindley I., Festus H., Samantha E., and Sarah E. There are to-day four sons living, viz.: Louis R., Benjamin R., Lindley I., and John W. The father, the subject of this sketch, lived to a ripe old age. He was a pioneer in its broadest sense -- in the opening up of a new country, in the establishment of educational facilities and religious work; he donated the land for the church and school house at Franklin Chapel, took care of the Methodist pioneer preachers, was one of the early Justices of the Peace, and did quite a lively business in tying the nuptial knot for the pioneer lovers. The fee for marrying a couple was $1., and frequently the groom would work for the Squire three or four days to pay him for the ceremony. John Walker was the County Commissioner, elected on the Whig ticket, and served on the Board with Peter Looney and George Mull. He was then a young man, and was Commissioner before the Mexican War. Was Captain of the militia in his township, and while in Ohio was enlisted in the War of 1812, under what was known as the General Call. He received his education in the pioneer schools of Ohio, was industrious and frugal, and at the close of a busy life he beheld in part the realization of his hopes. He died September 27, 1875, and lies in the burying ground at Franklin, with which spot he had long been familiar. After the Republican party was formed, he acted with, and voted for, his principles.

JDH: It goes on with a sketch of John Walker's son John W. Walker, and here is the relevant first part:
John W. Walker, son of John and Eliza R. (Jefferson) Walker, was born in Fayette County, Ind., March 14, 1821, and when about two years old, came with his parents to Ripley Township, Rush County, a then unbroken forest, and settled near Blue River, on Section 35, now the home of his son, William L. Here he assisted his father in his work of clearing up a farm, and attended short terms of school in winter.

NOTES (JDH 9/26/2003)): Lyon's Station (now Lyonsville, Fayette County, Indiana) is about 1 mile from William Walker's 1821 land purchase. See "1856 Plat Map". Lyon's Station is where the railroad crosses from section 22 into section 23. William Walker's 1821 land was in the SE corner of section 21 where it shows his son Samuel's name. Just north of Lyonsville, in the lower right corner of Waterloo Township, section 15, is the Springersville Cemetery where many Walkers are buried.
John Walker's son John W. was born in Fayette County March 14, 1821, apparently at Lyon's Station. John W. was 2 years old (1823) when the family moved to Ripley Township in Rush County onto nearly a full section of land. David Hartzell's brother Leonard bought land in Ripley Township in 1840 (1/2 mile from his 1832 land), where I think David lived at first. David Hartzell had a close relationship with the Walker family, and this may be where it started.
