This family is really confusing me

There is no correlating birth record with correct parents, no census records, they are noted as living in Limerick but married in Tralee, i’ve tried to look for death certificates for both Patrick and Johanna in Limerick or Kerry and found nothing, John is not noted as being 40 on his marriage record, he would’ve been 90 when he died but is noted as 74.
The only theory I can suggest is that the John that was born in 1879 died young and the name was reused, however I can’t find any death certificate

Do you have any pictures of him? Maybe folks on the photograph dating part of the website could try and estimate his age at the time of the picture? I think the 1926 census could help your problem but we might be waiting a while
