January 10, 1856Event
Thomas bought a "spotted hog" for $5.25 on nine months credit at the estate sale of William Flanagan, held by son and estate administrator James Flanagan. The first choice "fat" hog sold to William Osbourne for $13.75. Osbourne also bought the second and third choice "fat" hogs for $11.12 1/2 and $9.12 1/2 respectively. By looking at the appraisal of the estate, it is likely that the hog Thomas purchased was the Flanagan's brood sow.
