HIRAM T. CLARK, dentist, Ravenna, was born December 3, 1838, in Ravenna. His father, James A. Clark, came here from Talimadge (now in Summit County, Ohio,) and married Miss Mary Torrey. He carried on a wagon and carriage shop in partnership with his brothers, Newell D. and Miletas. James A. Clark died in 1852, and his widow afterward married a Mr. Goldsmith. She is now residing in Cleveland, Ohio. Our subject resided in Belleville, Ontario, from 1859 to 1867, where he learned the profession of dentistry. He remained in Wadsworth, Ohio, two years, and then located permanently in Ravenna, this county, in 1869. Here, by his scientific skill in his profession, he has built up a large and influential and lucrative practice. The Doctor was married June 6, 1868, to Miss Angeline Gilbert, of Belleville, Ontario. They have one son — James Gilbert. Dr. Clark is the only dentist in Ravenna, having obtained a certificate from the Ohio State Dental Society. He is one of the leading members of the profession in northeastern Ohio.
