Until anyone more local catches up with this post, I can telll you that there is a Headlam Rd and a Headlam Court in the Tilery district of Stockton, but this area has been redeveloped in recent years.
It looks as though the nearest RC church now, is St Mary's, Major Street (details from the RC diocese of Hexham and Newcastle) though whether it was in 1918 is another matter.
Hope this helps in the meantime,
