does anyone know what happened to the brother of ernest cleator moore (brought up on the pulrose estate from 1930 until about 1944/45/46)

son of christine/christian moore and jack cleator (not married!)
chris lived next door to about 5/6 of her sisters including winnie (cregg?) and dolly

from what i can gather, his brother was adopted at birth but no one seems to know of his whereabouts or even his name!
