Came across your email today purely by coincidence.
I was a Lockyer before I married.
My family tree shows my father Bernard John Lockyer, his father Herbert John, Herberts brother Edward Thomas (Titanic) his brother Ernie, another brother Albert, a sister Mary and there could be another sister. I have a few little bits of info re this but unless we can confirm a connection will not bother you with them. Please email me back if this ever reaches you--see it was posted 5 years ago!!
