Hi I am searching for any information on g-g-grandparents. Joseph Brown born 1811, County Monaghan married July 24, 1840 to Agnes Todd born 1819. Also and researching William Stewart b. 1822 and Isabella Irwin b.1831. Emigrated to Canada and were then married in Philadelphia before settling at Vasey, Ontario Canada. I believe that Isabella Irwin came from county Cavan. Thanks Leslie.
