Hi Suziq, are both the location of birth and the address of the person who registered the birth (probably "Alice"), the same?
If you or the other people working on this family can find his birthday from somewhere, that would help.
Certainly I cannot see a marriage or death for this boy under the surname Collins.
Haedocke is how Frederick's death is registered (in 1916). It may be worth seeing if he left a will.
