Ann Lahy/Lahey, wife of William Coil/Coyle

On 29 September 1846, William Coil/Coyle, son of Thomas Coil and Ann Wellworth “du comte de Tipperary” (of the county of Tipperary), married Ann Lahy, daughter of John Lahy and Ann Fitzpatrick, also of Tipperary (“du même comte”/of the same county). Witnesses to the marriage were John Doherty (Dogherty/O’Dogherty) and James [Brogan? Bingham?]. Marriage record found in the parish register for Notre Dame Basilica, Ottawa:

Ottawa; Ottawa (basilique Notre Dame), Register of Baptisms, Marriages, and Burials, 1845-1847, M. 81 (1846), Wm Coil and Ann Lahy, image 98 of 181, Ancestry.ca (http://ancestry.ca/: accessed 3 April 2011), Ontario, Canada, Catholic Church Records (Drouin Collection), 1747-1967.

Given the common surname and the common county of origin, along with their shared settlement in the Bytown area, I wonder if this Ann Lahy was related to my Lahy/Lahey ancestors who emigrated to March township (Carleton Co., Ontario) from Ballymacegan, Lorrha, Co. Tipperary?
