Looking for Quinns from Ballyporeen

My g-g-grandfather John Quinn along with his wife Ann Barry, and his brother Daniel and his wife Johanna Hackett, emigrated from Ballyporeen to Worcester, Massachusetts about 1851. I believe his sisters Bridget (Quinn) Keefe and Margaret Quinn also emigrated at about that time also.

John and Daniel died in 1885 in Worcester.

I am searching for information on their parents Dennis Quinn and Mary Griffin, who are listed on Daniel's and Margaret's death records.

I am also searching for any related Quinn still living in the Ballyporeen area.

Thanks very much for any help you can offer.
