Born in Fairfield county, Ohio, in 1833, he was relocated to Elkhart county, Indiana, in 1835 when his parents became early settlers of the area.
Bartlett went to college to study medicine and became a respected physician in Indiana. He married Sarah Miller, the daughter of the founder of Millersburg, Indiana, and they had seven children--none of whom, so far as I can tell, was a doctor or dentist.
Still, Bartlett Larimer's dedication and success must have inspired the sons of his sister (Margaret Larimer, who married Thomas Short). Two of these nephews became doctors after getting degrees and studying under their uncle's tutelage, and two of the nephews became dentists.
