I do not have information on Throckmortons you have mentioned. However, there are Throckmortons in my husband's family. In fact that is his middle name.
I can find info on Albion (a name of my husand's fraternal uncle) Throckmorton and his wife, Mary Smith Webb. There is obviously a generation missing in our records because it indicates their daughter is Lucy Smith Throckmorton and the dates do not add up. She married Rev. John Ryon. We have letters stating she was a brother or cousin of James Webb Throckmorton, who was Gov. of Texas. His father was William Edward Throckmorton, born in Sparta, Tn. Migrated to Fayetteville, Ark. Then after his wife died, he married Melina Wilson and shortly moved to Collin Co, Tx.
James returned to Ky. at an early age and studied medicine with his uncle, James E. Throckmorton in Princeton, Ky.
If you have any infomation on any of these Throckmortons, we would appreciate it if you would share it with us. Thank you.
