DAVID M. LOGAN, physician, Newmansville; was  born in 
Belmont County, Ohio, Jan. 4, 1821. In 1836 he came with 
his parents to this county; they located on the Sangamon 
bottom, near Beardstown, and engaged in farming. James 
Logan, subject's father, was born in Huntington County, Pa.
The family is of Irish descent, and some of the ancestry 
came to America in 1775. Emma Collins Logan, the mother of 
our subject, was a descendant of the Tillinghast, Collins 
and Green families, of Rhode Island. She was the mother of 
eleven children, of whom the doctor is the fourth.  At the 
age of twenty-one he began teaching in the Beardstown
schools; the principal part of his education was obtained 
in the literary department of the Illinois College; he 
attended his first course of lectures in the Medical 
department of that institution. In 1857 he graduated at
the St. Louis Medical College, receiving his diploma as an 
M. D., and immediately entered upon the practice of his 
profession at Newmansville, where he has since remained.
He married in this county, Jan. 20, 1858, Miss Rebecca W. 
Hamilton, who was born in Loudoun County, Va., June 20, 
1830; they have six children, viz.: Sally, Edwin M., Emma,
Stella, Charles C. and Agnes; the two latter deceased. Mrs. 
Logan is a daughter of Charles B. and Sarah C. (Lucket) 
Hamilton, natives of Loudoun County, Va.; he deceased; she 
is still living. Dr. Logan was at one time a member of the 
I.O.O.F; he is a Republican.
