Yes , of course, I realise that.
Here is Michael of Clone with father Denis.

However, we are digressing.

I think I can say that the Denis Mordaunt  living near Monamolin was not OP's relative or ancestor, unless there has been a massive memory loss in the family.

For the same holding that Denis held in 1852, in 1846 we see Denis crossed out, and Admiral Francis Mordaunt written in.

Just to clarify this.

I think it reads Admiral Francis … and is continued in the indecipherable writing - ‘..tton’.
Mordant is struck through for Denis and Mordaunt written as the correction.
Two separate entries.

Looking at Griffiths for Dennis in Clone - the lessor is Francis V Hatton. (Various references and biographies elsewhere).

You are correct.

I thought "Denis" was also struck through. But on second look, it seems to be an artifact of the way Denis was originally written, plus the diagonal lines through.
