Caution.
First of all, these situations are volatile.
Secondly, it probably won't fix the problems with your children. If you don't see that the reason your children aren't catechized is likely your fault, and that your problem is in the home, the only person who can truly resolve this is you. Teach them yourself, get rid of whatever is replacing catechism lessons in the home.
Don't move for the mass without other considerations. You may end up in a situation worse than where you started. Many people move to Omaha, Cincinatti, Spokane, etc. with their children in hopes of correcting wrongs they have already made. It doesn't work out well, often, especially if the children are older. Most people with older children are not financially situated to bounce back from a mistake. Also, in these situations, men have often given up stable jobs and family support, only to flounder in the new location, and cause their families to suffer. Some even move back to where they started.
If you are bent on following with your wagon to Pfiefferville, at least wait a few years to study the situation, talk to people, visit, let them go through their growing pains-- and then evaluate.
