Initials inscribed into stone of bible garden gate?

[MPRob]

Whilst searching for further numbered stones around the cathedral area. I came across what looked like the litters I J inscribed into the stone of the gate into the bible garden.



Are these mason marks? Or something else?

Best guess here is a stonemasons mark. Given the font, relative obscure location etc. We know it was erected in 1812 by Bishop H W Majendie with ironwork by Mersey Foundry, Liverpool as the entrance to the Bishops Palace gardens.... but i don't know who the builders/stonemasons were.
