Harding's History of Decatur County tells us a bit more. At p341 he
says "It is not certain who was the first physician in Decatur
county, but it is know[n] that Mrs. Justus Rich practiced medicine in
Greensburg as early as 1821 or 1822. Other early physicians were
Conduit, Gillespie, Hartley, Teal, Lyman and Stubinger." Apart from
Gillespie, this is a list taken from the 1882 Atlas of Decatur County
p76; Mrs Rich also appears in the Atlas at p9.
As we know, Harding isn't always consistent. At p351, he says "Dr.
Jesse M. Gillespie was, perhaps, the first physician to locate in
Greensburg, as he was here prior to the year 1825. He built a brick
residence, the second one in the town, in 1826, on the south side of
the square. He died in 1833, and his widow married Mr. Thomson."
On p219 Harding quotes the autobiography of Rev. Joseph Tarkington:
"The fall of 1833 conference was held at Madison, and I was sent to
the Greensburg circuit. When we came to Greensburg things appeared
discouraging. The town had been visited by typhoid fever and many
had died -- Doctor Teal, George Robinson, Mrs. Silas Stewart and
others [including Dr Gillespie above?]. There had been no religious
services for some time. There was no Methodist church. . . It was a
long time before Silas Stewart got restored from his sickness to
health of body and mind. Until he got to walking about he thought he
owned the town."
