Thanks everyone, especially Monica - yes I have the information that you have offered. I know from the 1851 UK census that William Sweeney was born in the West Indies and I have a copy of his original marriage certificate in 1834 when he married Sarah Collins, unfortunately it doesn’t give any details whatsoever about his date or place of birth, or his fathers name ..
Does anyone know where birth records for the West Indies are held .. or do I need to know exactly where in the West Indies, e.g. which island he was born?
