Thank you so much. I went to the emerald ancestors site but couldn't find any mention of the directory you mention. But, if that is my Henry, he must still have been alive in 1846. Another clue..... :o}
I checked the site for a birth record for Emily but nothing. But the family might have been from Belfast but Emily might have been born in Dublin.... Or it could have been the other way around, the family was from Dublin and moved to Belfast.....
The other site you mention is that for all of Ireland? I can't remember the name of the site at the moment (I am at work) but if it is the one I am thinking of I believe I tried there for Emily's birth (and Henry's marriage as well). Hopefully, there is another site to check.
But thank you so much for this latest clue!!!!!!! Maybe I can try and research that address. Something might turn up from that.
