Charles Henry James Smith

Dear Maggie, My great grandfather was Charles Henry James Smith & I wondering if you could give me anymore details surrounding his adopted sons - One of which was my grandfather Leslie. My father lived with his grandmother Agnes Smith (nee Goddard) and remembers talk about the Titanic. I have been tracing my family tree for over a decade, but could never find a birth certificate for my grandfather Leslie. This could explain why. Any help would be much appreciated! Many thanks Leigh xxx
