YES , Tyster , you can have as many Roth IRAs as you want . I , myself , have three Roth IRAs with Fidelity , Schwab , And Vanguard . I do intend to consolidate them with two custodians in the future . And , in the end , I may decide to have just one single Roth account with one custodian , probably Vanguard .
My wife also has her own Roth IRA account with a single custodian .
As you are married , your spouse will be your automatic " named beneficiary " . In the event of the death of the account holder and when the account passes to the spouse who is the automatic beneficiary , PLEASE designate a new " named beneficiary " to that account cause in the event of that last person's death , the account will pass to heirs and they may have to take those funds in as little as one to five years depending on the different circumstances .
My wife has instructions in the event of my death to " rename " my accounts ( IRAs , Roths , 401(k)'s ) in her own name as soon as possible and then to specificly designate a " named beneficiary " to her new renamed accounts . And , in the event of my wife's death , I will go her Roth account custodian with a death certificate and " rename " her account in my own name and name a specific " named beneficiary " for my newly named Roth account . I would do the same with my wife's IRAs in the event of her death , but she's already converted all her deferred accounts ( IRAs ) to Roths .
PLEASE see a CPA or a qualified tax person ( not me

) if you don't understand the importance of this . And I'm sure there'll be other more qualified folks here who will answer your post too . You've definitely come to the right board forum to get excellent advice on matters like this .
