Hello niggywiggy
This means "The Drowning Pool". It could be a placename.
As you'll see in my sources below, there is more than one way of
spelling the word for drowning. I found it online as:
bhàthaidh
bàthaidh
bàthadh
bhàthadh
I didn't find it ending in "d" without a final "h" as in your version,
but am confident "the drowning pool" is the correct meaning, as there
isn't anything else it could be.
Poll can also mean water-hole, bog and other wet places.
Scottish Gaelic words starting with a simple "b" change to "bh" in
some circumstances, but you need to look them up in the dictionary as
if they had no "h".

The previous page appears in Gaelic as:
"18mh dhen Dùbhlachd 1862, latha air a bheil cuimhne fhathast mar 'Là
a' Bhàthaidh Mhòir"

I hope this is helpful, but let me know if you have a query about my answer.
