Right Anthony,
We need to go back a bit in time here to see when the Houstons appeared on the Crumlin Road.
Could you look in your directories from 1880 to 1920 please? I have already looked at this site -
http://www.lennonwylie.co.uk/ccomplete1880.htm Look what I found.. 6, Crumlin Road, Civil Service & Military Academy, Frederick H. Houston, Principal
Joe, do you think this guy is an ancestor too. Would you please have a look at the Crumlin Road for more Houstons. I do not think I missed any but you never know.
I also had a look at this site -
http://www.lennonwylie.co.uk/alphanames1880gh.htm This gives me a bit of a puzzle. Houston, George, red tape manufacturer, 25 & 27 Melbourne Street. Now why limit oneself to the manufacturing of red tape only? It does not make much sense to me. Why not a whole lot of colours?
All the Best, Chris
