Hi again, thanks for the extra information.......but it's still not clear what you're after....by 'his family' do you mean any or all of:
* He and wife & children from the mariage forward? (possible privacy/living issues therefore, with naming any children on this forum)
* His natal family going backward and/or forward : ie his parent's background, what became of them; what became of any siblings)
* His wife's natal family going backward and/or forward? ie her parent's background, what became of them; what became of any siblings)
Do you have him on Census 1891 and 1901?
Do you have his birth, death & marriage certificates?
A will?
Cemetery records?
Military records? (WW1?)
And, born in Torry 1883. Kincardine? Aberdeen or Fife?
I had a quick look on Census and didn't immediately see him coming up.
SP Index search shows 2 William George SLATER's were born between 1882 and 1884 - both in 1883. One registered in Kincardine. and the other in Banff.
