You need to include any dates or approximate dates that you might have related to Quinton's birth/marriage/death.
Do you have the names of his parents, siblings, children? Any clues to aid in this search?
And also - as you have stated - the one from Ireland - is Ireland the location of his marriage? Or did he come from Ireland and move to somewhere else when he got married?
If you have a WikiTree ID, include it in your question.
Add any dates - as no one can tell if the Quinton you are searching is from the 1800's or the 1980's!!
And if he emigrated from Ireland - put to where - as he could have gone to the US/Australia/ or some place else!
