You're in the right time frame for my Glassey, though I don't yet have anything much to go on. Evidently the name was common but not wide spread in Armagh. I will look to see what else I have been sent by others a couple of years back.
Mary Jane Glassey married my Gt gt grandfather James Allen in Armagh in1834. So far searches have not unearthed M-j's line.
\as we are both in Montreal we could comunicate more directly if you wish.
