The Forey sisters were Frances (married name Matthews) bn 1831 a soprano, Mary Ann (Kruger, later Kruger-Evans) bn 1834 a mezzo-soprano and Sarah (Hellerman) bn 1841/2(?). Their parents were Frederick Forey and Margaret (nee Williams). Frederick was born in London and came to Wales with the army, first to Brecon, then to Merthyr. The sisters were very successful, winning many Eisteddfod prizes. This information was sent to me by Tom Marston who is a descendant of one of their brothers.
