I only have a partial copy of the 1830 "Tithe Valuation & Applotment book of Loughgall"
The valuation has been filmed and is available through the LDS library, film number is 0258463. The Loughgall valuation is almost at the end of the reel. There are both Reilly's and Dreany's listed in the parish of Loughgall. I also have additional information on the daughters of Henry Dreany and Sarah Reilly that emigrated to Australia.
It would be easier for me to share this information with you if you subscribed to the following DREANY mailing list.
To subscribe simply send an e-mail to: DREANY-Lfirstname.lastname@example.org
with the single word "subscribe" in the message body (and no other words), RootsWeb will automatically sign you on. If this is a problem let me know here and we will think of another way to get this information to you.
All the best,
