I can tell you something about Philo (Philander) Hoadley of Delaware Co, Ohio:
Philo: b. 12 Oct 1763, d. 1847 Ohio. He is also in the 1820 census for Berlin Twp, Delaware Co. (p 118 - image is on Ancestry.com census images) His brother Chester also in the same Twp in 1820. Philo married Esther Hine in 1783 in New Haven Co, CT.
Parents: Ebenezer Hoadley b. 18 Mar 1738/39 Branford, New Haven, CT, d. 24 Sep 1814 New Haven Co, CT & Sarah Lewis b 9 apr 1743 New Haven Co, CT, d. 22 Jun New Haven Co, CT.
Philo went from CT to Delaware Co. about 1808-09: here is a portion of an account which I found on the Internet about them (I am researching Lovell Caulkins, who came with him):
"The Hoadleys and Scott, anxious to secure a soil less sterile than their native State presented, were glad to believe the exaggerated description of the West, and, purchasing their land, started in two wagons. Philo Hoadley, besides his wife and three boys, afforded accommodations for Lovell and Lucy Caulkins". (Look at this site which has a ton of info about this group - Hoadley, Caulkins, Lewis, etc. http://www.heritagepursuit.com/Delaware/delindex.htm
So, I don't know if the Ohio Philo was the ancestor of the one who would up in Texas, but he is definetely the one who came from CT. If you need more info/sources/ or further back in Ebenezer's family, reply to this message.
