Matilda McKimm born c1846

Confused now 🤔 haven't had a chance to look yet but are you saying there were two John Tates? One who married Isabella McKim (sister of Matilda) and one who married Eliza Warren McKim (ah as she was James McKim's daughter she would have been Matilda's niece and not any daughter she might have had!)
Age would be incorrect too. Shouldn't jump to conclusions before finding all the evidence... My bad!

Kathleen TATE was the daughter of Dr John TATE and Matilda’s sister Isabella Marion

Phone acting up or I’d add link to her birth and their marriage which was in St Peter’s in Dublin.

So now I've had a look and I'm not quite so confused
Robert Tate (who married Eliza Warren McKim) and John Whittaker Tate (who married Isabella Marian McKim) were brothers and sons of James Tate. Eliza Warren McKim's father was James McKim and Isabella's was Patrick McKimm.
Isabella Marian Tate died in 1889 at the age of 36 of chronic bronchitis.
