The football bug has bitten me hard...
Is Drew Brees or Archie Manning the patron saint of New Orleans?
SERIOUSLY... The selection of a 'patron saint' for me (my Confirmation Name is Joseph) came to me because that was my godfather's given name, Joseph was Jesus's 'godfather,' and both my godfather AND my actual father both worked in construction (as did Jesus's earthly dad). I also work in construction.
A patron saint can have meaning for you because of your occupation, or the life of that particular saint inspires and appeals to you. Perhaps a saint associated with the country you live in, or the nation of your family's origin.
There are many ways you can select one.
Having said all that... The BEST thing anyone can tell you on this topic is that when you find the right one, you will know.
