Yes, there's info in the book on Hugh Meighan and Elizabeth Casner. You should be able to get the book through interlibrary loan no problem - that's how I first saw it.
Hugh & Elizabeth are on page 45 of the book; Hugh is "M32" in the book's numbering scheme. Here's what the book says:
"M32 - Hugh [Meighen]; married Elizabeth Casner. Hugh was born on May 20, 1802 and died on April 14, 1860. His wife was born on September 24, 1813 and died on April 11, 1879. Both are buried new Chillicothe, Ohio (166). Hugh was a farmer and was buried on his farm (199). The burial site is called Tuvell Cemetery and is in Ross County. Hugh was unmarried in 1836 when he suffered a broken leg and recuperated in the home of Enos Rheinhart (M36) (244 plus 473). Another report says that Hugh died on April 15, 1861 (263)."
The numbers in parentheses refer to his sources, listed in the back of the book.
Hugh's parents are listed as John Meighen and Christena -- Meighan, and there is information about them, all of Hugh's brothers and sisters, and Hugh's grandparents -- John's parents -- James William Meehan and Susan McCloskey Meehan -- that's the couple with whom the book starts.
Hugh and Elizabeth's children & descendants are also enumerated in great detail.
Good luck getting a copy! In the meantime let me know if I can look anything else up for you. Also, I may be able to help you find a copy to buy if you want to do that -- email me at email@example.com for info.
