Welcome to the forum! I'm thinking the mark looks like an "ALP" or "APL", at least that's my interpretation of it. I have been searching a bit and can't find the mark yet. Hopefully others can chime in and help us both out!
Only one I found that fit was Anchor Porcelain Ltd !! Would have made all kinds of stoneware & porcelain items !!
This may help a bit, the style of your bowl is considered "Belleek", this style was big in Ireland, have not got a chance to look for the hallmark, but thought this may help a bit in the search.
