Dear Wyseass,
The same symbol appears on the Mathews Signet rings.
I had one & my Brother,Rodney, had one also.
There could be a connection also, to Masonry, Marcus B. Senior was quite high-up in Irish
Masonry.Exactly what position I dont know.
My Mother was in possession of her Father's regalia,Sword etc. What happened to it all, I dont know,my Brother & I were not allowed to play with the bits & pieces,for obvious reasons!.
OK,
Brian McDonnell.
PS. I have just remembered---my signet ring actually belonged to Marcus B. Senior,my Brothers was a copy.
PPS. My wife & I also have a few pieces of Mathews Silver----Teapot,Cream jug,sugar bowl & cutlery----all with that Symbol engraved
on them,passed-on by Mother.
