I am researching the Mantecon family name for my mother-in-law. Her name is Lilliam Gorgina Mantecon and she was born in Camaguey, Camaguey, Cuba. Her father was Bienvenido Mantecon Cueto and born in Santander, Spain. He had a brother Manuel and a sister Abelina. Their father was Felipe Mantecon Casuso born also in Santander, Spain. Any info would be appreciated. Please visit my website at goofygoffin.homestead.com. Thanks!
