We understand most of main body; however signature and place are a mystery

If a word at the end of the second line of the text begins with a capital C (Carpenter?), then I don't think this can be Castle.  The letter appears very different.

Also one of the things that this writer did do was cross his t 's

Not much else! The letter you were hoping was a 't' in castle does not seem to be crossed.

You're quite right! I agree...

true! - but I wasn't hoping for anything particular really. This is a puzzle. I'm just waiting to see where it goes. It would have been too good to be true if it were Castle Park

On Griffiths Valuation in 1850 there is a Daniel Foley in a place called Fethard in Co Tipperary.

The two words that look like Martha Park

The first letter of the second word must be an I.  At least that’s how I was taught to do capital I in the olden days.

Do you mean the first letter of the second word of what I assume to be the signature? The one with a wide underscript swinging to the reader's right, and comes back again to the second letter?

Any idea of what that second letter would be?

I saw that - my Daniel went to the USA in about 46 or 47 but it could be someone related to him.

We have some other papers that seem to place him working for a Michael Green, who is a landowner in Golden Tipperary. So I think the Foleys in Cashel (horeabbey) are the ones, but can't get any further than that at the moment.

If I may take the liberty of first answering for Mckha, I think his or her post refers to the letter in Signature_Section_Initial.jpg as attached.

If I read you correctly, you are referring to the section in Signature_Flourish.jpg as attached.

My interpretation of this latter section is that the forename ends with a superscript contraction as was common in this period.  Common examples are J^no, J^as & Tho^s.

I think this one ends with a y, and the underscript (as you describe it) is a flourish, continuing from the tail of that y and joining onto the first letter of the surname - which is probably T.

Finally, regarding the letter in Signature_Section_Initial.jpg, it doesn't look like the I in what I think is ...I believe him... in the main text above.

I posted the same question on Reddit. Here are some thoughts about the text from that string
