Had a look at Bella Vista on the map, it was a fairly big house.
The Matthew in Templeogue in 1901 and 1911 is living in a 1st class, 14 room house. He also owned several other properties of his neighbours. (House and Building Returns)
It doesn’t look like he filled in both forms himself, the hand writing is quite different, I think the 1911 one is the enumerators writing which may explain why he is listed as single.
Of course the ages on the census don’t come close to the age of 81on the death certificate but given the size of the house and other properties it must be the same man.
His estate was worth over £5000.

Which leaves Frank F, where did he go?
Does that sound correct?
The property in Templeogue would be worth looking at. See next reply.
