I can't believe we found what we have found so far, Thank you so much.
The marriage of John W Goss to Agnes E McDowall has to be the correct marriage in 1941.
There is one other Liverpool 1944 marriage of a John H Goss to - spouse's surname is Halewood, but I can't find a Liverpool birth for Halewood. So I doubt that would be the correct marriage, John's second initial doesn't fit.
I've looked for births of siblings & can find only 2 brothers, can't see any sisters! So maybe it was Agnes's 'brother' & his wife who brought up their sons. All a bit vague, because one of the articles says their 17-year old son was staying with 'friends' of the family on Eighth Street, Long Branch in Toronto, while finishing his education. Maybe 'friends' were actually 'family' on Eighth St ?
If so, we are be looking for the name McDowall
The brothers I've found are;
J**** McD***** born 1920 Liverpool
W****** McD***** born 1924 Liverpool
They could still be living so can't put full names on here, but J & W are very common first names.
