The info that I received from Margery Hayward [Mitchell decendant] was that Allen b. 1790 lived in Keady, near Crumlin, left Belfast aboard the boat Miltiades - May 8, 1846. The voyage took about 6 weeks and they settled in Montague, between Smith Falls and Brockville. There is quite a lot of history on the Mitchells in Marybourgh Twp. There were 9 children. Allen died Nov. 15, 1856 age 66. Married Mary Mitchell b 1803 d. Aug. 14 1861 age 58. Margery notes that names dates and ages were taken from the tombstone in Derryadd Cemetery, Rothsay, Ontario.
