Brennans and Mulligans

[NineTails]

I’ve managed to trace back as far as Patrick’s parents; James Mulligan and Catherine Keely. After that, things get hazy. Someone helped with some research a while back, and said that they’d found siblings for my great grandfather Patrick; Anne, Catherine, John and William.

Margaret’s father is named as Patrick on her marriage certificate, yet there’s also someone by the name of Simon Mahon that pops up in searches.

On a quick search, i can see siblings, Catherine, Ann and William.
James and Catherine married pre civil records so you will be relying on parish records.
Here is James’ death where you can see J Keely, brother in law, is the informant. That may help you work back.

That’s him. His father(according to earlier research) worked at Silveracre House as a groom.

And his Godfather is James Keeley

So the problem is the age on his death cert yes?
His newspaper notice says buried Mount Jerome but I can't find an image of a headstone which might have a different age on it.

How sure are you that it's the correct Patrick Mulligan death cert?

He passed away just before before my mother was born; her birthday was April 12th, 1941. Plus his address at his time of death was where he’d lived and worked since the mid 1930s. My grandparents, Patrick Brennan and Mary Catherine, lived in 276 Harolds Cross Road until about 1940, when they moved into the married quarters at Cathal Bruagh barracks where my grandfather was stationed.

Looks like your best bet would be contact Mount Jerome and hopefully they can find Patrick in the burial register or a headstone with an age and also confirm when Margaret died as she doesn't appear to have a death cert or death notice.
It's most likely St. Kevin's hospital just made a mistake on his death cert.
