Some records show ‘alive’ or ‘dead/deceased’. Others don’t but it doesn’t mean that the person was alive at that time.
I think you have reversed the birth year for William - should it be 1856?
You would imagine that there would be births between 1851 and 1855 but there does seem to be a lack of records.
Godparents can be useful in case they are family and would spread the search wider.
What do you mean by ‘William had some connection to Tipperary’? Where did that information come from?
It’s a bit vague.
