Here is what I have that might be of interest:three parishes in County Derry had a large number of Earle/Arrell/Orrel folks, Maghera, Magherafelt, and Termoneeny.Termoneeny is situated between Maghera and Magherafelt.
There was a will for a Robert Arrell in 1747, and for John Arrell in 1819, both of Termoneeny Parish.
The 1831 census of County Derry showed two John Earle families in Tamnymullan Townland of Maghera Parish.Also in the same Townland were one David, one Thomas, and three James Earle families.
The 1831 census of Cabragh Townland of Termoneeny Parish showed (all shown as Presbyterians) Thomas Orrel with 2 males and 3 females, Robert Orrel with 2 males and 2 females, Sarah Orrel with 2 females, another Robert Orrel with 1 male and 1 female, and a John Orrel with 6 males and 5 females.
After checking my files, I think you would really enjoy getting the following book on interlibrary loan.It is over 700 pages and is the definitive work on these Ulter Earle/Arrell folk, as well as a lot of data on North American descendants.It has marriage info from Ulster, much too numerous to mention in today's note:
"The Arrol, Arroll and Arrell Families" by John Arrol and Robert N. Arrol, M. D.ISBN # 0-963987-0-X, Library of Congress # 93-74724.
