Thomas Collings (10/11/1760-10/03/1842) was given a 400 acre land grant for serving in the 5th Pennsylvania Regiment in the Revolutionary War. The allotment was for then Jefferson County, Kentucky at the "Crooked Run" watercourse.

He died 10/3/1842 in Jackson Indiana
His father was William Elston Collings (12/11/1724-12/11/1787) from Frederick Pennsylvania. He died in Nelson Kentucky. William also served in the 5th Pennsylvania regiment in the Revolutionary War. He also applied for a land grant. Though I can not yet find where it was alloted.
It looks like this portion of the tree down flirted with Kentucky, Indiana, Missouri, and Kansas from then on. The name Collings in my liine ended with David Collings (1788-01/07/1852). His son William Buford (11/17/1811-10/22/1876) is always listed as Collins and not Collings.
