Hi: Although they sailed from Dublin, Ireland, and not England, I do have ggrandparents John and Mary Clarke, who left Dublin in 1833 for Canada. I have no record of any siblings but my grandfather, Daniel Marron Clarke, was born at sea on April 25, l833, a surviving twin, and named Marron for the captain of the ship. Considering the large families my Clarks have had, I would be surprised if Daniel Marron was an only child. My John and Mary settled first in Peterborough, Ontario and later were in Durham and Simcoe Counties. Could we have a connection? Let me know, Jeanne
