lerlen on Family Tree Circles

Hi. My name is Lerlen La Foy and I am looking for
relatives of my dad's (Colin Robert La Foy) with the
surname LAI. My great grandfather's name was FOY LAI.
He married my great grandmother MARIA ELIZABETH MANUEL.
Their children's names (Chinese in brackets) are:
Nicholas (Kwok Chong), Elisabeth (Nuk Alaan), Rosie
(Nuk Hinkie), Doreen (Nuk Wa), Henry (Kwok Ming), Manny
(Kwok Sing), Stephen (Kowk Toy), Stella (Nuk Lien) and
Clarence (no Chinese name). They changed their surname
to LA FOY. Apparently my great grandfather went back to
China and took his eldest son with him, Nicholas.
Stella (Nuk Alaan) is my grandmother and she lives in a
home in Sydenham, Durban.
