Hi
My Dad's family are from Jamaica, last name of Valentine (they made a mistake on y birth certificate with the two lls) My dad's name was Vincent Albert Valentine
His father was Alexander Valentine, and his mom died during childbirth. I have an aunt (his sister) named Valerie Valentine and another one who I believe has the same name as your mother. I have cousins in Canada named Clive. If you get this email, send me an email (mvallentine@mindspring.com) because I know where most of the family is, even the ones in Costa Rico and can put you in touch with most of them
