Lawler/Pike/Sweeney

I am looking for information about Lawler's, Pike's and Sweeney's. Dennis Pike (1812 born in Ireland) and Ellene Sweeney (1816 born in Ireland) married and came to USA around 1840 and settled in Schuylkill, Pennsylvania. I would like to find out where they were from in Ireland.

Their daughter, Annie Pike (1832 born in Ireland) married a man named Lawler who was also born in Ireland. I have no first name for Annie's husband. They eventually had 5 children an she and her only surviving son, Michael, settled in Cincinnati, Ohio. Michael was my great-grandfather.

Any information on any of these people would be greatly appreciated.
