Hickey

I am trying to find the husband of Johanna, the widow Hickey. She sailed to Ontario, Canada with the Peter Robinson Settlers in 1825, taking her six children. Be believe she was either the daughter or a close relative of James and Mary Flaherty, also, PR Settlers. They were from Kilworth Parish, but we believe they lived in the Araglin area. It seems that there were several members of a Hickey family in the Leitrim area at about the right time. Is it possible there is a connection to Johanna? I would appreciate any records you know of or research suggestions. Thank you. Elsie Hickey Wilson, Wisconsin, USA
