Individual Details

Martin married Jane Forester about 1809 - she died in Lawrence Co IN about 1830. She doesn't seem to be in the census for that year.

1830 Lawrence Co IN Census:
Martin Flinn: 1m 5-10, 2m 10-15, 1m 15-20, 1m 30-40. 1f 5-10, 1f 10-15, 1f 15-20.

Martin married (2) Eleanor "Nelly" Crawford, 17 Jun 1830, Lawrence Co IN.

November 1836, Lawrence Co IN, probate records, John Guthrie appointed administrator of Martin Flinn deceased. Named heirs Melinda Box, Jacob Flinn, Hiram Flinn, Rebecca Flinn, James Flinn.

Heirs of Martin received his share of his father's estate
"Each grandchild received $6.90."
The heirs of Martin were named in the settlement. These were: William, son of
Malinda and James Box, both deceased, paid to Guardian Thomas Box of
Missouri; James and Rebecca Box; Hiram Flinn; Jacob Flinn; Samuel and
Matilda Box; and Daniel Flinn."
My note: Each of the living children of Jacob received $48. It would seem that for each child to receive $6.90 he would have had seven children. I think that might be sons Hiram, Jacob & Daniel, William a son of deceased daughter Malinda Box, Rebecca Flynn who married James Box, and Matilda Flynn who married Samuel Box. However, that adds up to 6 heirs, not seven.
Online sources indicate that indeed both Malinda and Rebecca married men named James Box but they seem to have had different fathers and be two different men.
