If anyone out there has information on two sisters born in Canada around 1856 or 1857 named Mary A. and Marguerite Derrig please help me out. They may have lived in Kempville or Prescott ontario area in Canada. I am trying to connect them in somewhere. I know their family at some point in time had to descend from Ireland. I have tried to make some connections but I have been stuck for years with this. Thanks for any connections. Eve
