Sharavogue Townland - Kilcolman - Toher and Toole

My Ancestors William and Ellen Toole emigrated to Australia in 1842.  William's brother Martin and his wife Margaret (nee Tew, Toher, Toohey) emigrated along with them.   William and Martin's mother's name is Anne (nee Briggs) and Margaret's mothers name is Bridget.

A transcript of Martin's emigration papers says that both his father and Margaret's father are dead.

On William's emigration papers, his character witnesses Michael Parlon and Matt Keenan are from what I believe is Sharavogue.

In the Griffiths valuations for Sharavogue there are two women, Anne Toole and Bridget Toher.  I am wondering if these ladies might be the mothers.

Does anyone have a connection with Sharavogue and/or Anne Toole and Bridget Toher.

Regards,

Karen.
