WILLIAM A. McCONNELL.
William A. McConnell, now deceased, was one of the pioneers of McHenry County, became a heavy landowner of Richmond Township, and was intimately associated with its progress. He was born in Pennsylvania, was there reared, and came to McHenry County in 1837. The first settler to locate a claim in Richmond Township, he secured one on section 8, on which he erected a log cabin, 10x18 feet. Having thus provided a home for his bride, Mr. McConnell returned to Pennsylvania, and was married there in 1838, to Elizabeth Bodine. Returning with his wife, Mr. McConnell began to improve his land. For fifteen years the primitive log cabin served as a home, but it was then replaced by a frame residence, located across the street from the cabin. In 1872, a more commodious residence was erected on the site of the cabin, and there William McConnell died October 9, 1887, his wife passing away six months later. They were survived by three sons, namely: Abraham B., John and George, sketches of whom appear elsewhere in this work. William A. McConnell was one of the most influential men of his generation. During the administration of President Van Buren, he was appointed postmaster of Richmond, and served for six years, the post office being in the log cabin on his farm. He was associate judge of McHenry County for sixteen years and in 1844, he was elected county commissioner and served in that office until the adoption of township organization, when he was made a justice of the peace for Richmond Township and held that office for thirty-five years. He was appointed a judge of election in 1840 and served as such for several years. Mr. McConnell was a member of the first state legislature convened under the new constitution, and served as a member of the board of equalization one term, and as supervisor of Richmond Township for several years, and for one term was chairman of the board. He was a member of the Methodist Episcopal church, and was one of the organizers of the church of that denomination in Richmond. Not only did he serve faithfully and well in every office, but he reared his three sons to be as upright and capable as he, and they, too, have made their influence felt in the history of McHenry County, so that today the name of McConnell stands for the highest standards of American manhood and good citizenship.
