Find Ancestors

Completing a tree for my nephews 21st and lacking details on my mothers side. My mother was an only child from her fathers second marriage.As a baby cared for by her mothers sister and had very limited contact with fathers family.
Very recently found multiple graves in Llandaff Cathedral which gave clues to a much larger family.Including a half brother Tony Kelvin Reed and aunts / uncles.
Can anyone help fil in the gaps from the families of my Grandfather Albert 1922
