Dear Keith:  

Many orders have either a corresponding Third Order for the married laity, or a missionary cooperator program, or a Movement that shares their spirituality in which a married couple may participate. The degree of participation, and the corresponding obligations, will depend on the individual group. I would recommend that you get in touch with whatever religious order you are familiar with, or which attracts you. If you have no idea, write back and I will let you know some possibilities. But I may be misunderstanding your question. If you are asking about Holy Orders, and not religious orders, then you can consider that there are married deacons in the Church. However, it is usually only men who have successfully reared their families that are called to this vocation.

God bless.
