"ROBERT M. DELZELL, M.D., was born in Blount County, Tennessee, November 8, 1843, and is the eldest of the eight children born to WILLIAM and MARY J. (McTEER) DELZELL, both natives of Tennessee, and of Irish and Scotch descent. In about 1750, three brothers and a sister - JOHN, ROBERT, JAMES and ROSANNA DELZELL - came to America, two brothers settling in Pennsylvania and Virginia respectively, and ROSANNA and her brother JOHN in Tennessee, where she married HENRY FERGUSON, and from these brothers it is thought all the DELZELLs in the United States are descended. WILLIAM DELZELL followed tanning in Tennessee till 1851, when he moved to Crawford County, Illinois, entered 120 acres of land, and there remained until his death, October 9, 1851. ROBERT M. DELZELL received a good academical and collegiate education, and at the age of twenty began to make his own way through the world. In October, 1864, he enlisted in Company H, One Hundred and Forty-second Indiana Volunteer Infantry, and served until the close of the war, and was mustered out at Indianapolis July 14, 1865. In July, 1866, he came to Monticello, this county, and commenced the study of medicine with Dr. W. S. HAYMOND. He pursued his studies and taught school alternately until March, 1869, when he settled in Reynolds and began practice, of which he has now an extensive share. December 30, 1869, he married MARY E. BRISTOW, a native of Parke County, Indiana, who has borne him two children - ANNA L. and MARY E. The Doctor is a Democrat; was for six years Township Trustee; has for several years been Secretary of the School Board of Reynolds, and is a member of the Masonic fraternity."
