Thank you to everyone for your help.
These census records are so confusing. Is place of birth a mistake often made on census records?
Yes they did live in Middlesex when they first came over to England. Phillip worked for Thomas Telford and was chosen to work on the Menai bridge. This is why they ended up settling in Bangor North Wales.
Looks like the Irish records seem to be the problem as I can only find a Philip married to an Catherine Homes.
Once again thank you all for your help very much appreciated
