Best of luck to you and congrats on your soon to be marriage. 

They're newlyweds (2 years) so hopefully nothing happens to the marriage, but if something does there's no reason why they shouldn't be able to pay the lease through or an early termination fee penalty of 1.5 month's rent.Let all the concerned Aunt Suzies step forward...

That stress from hiding something will seep into your personal relationship with each other and damage your marriage. 

On the matter of equality and quality of life for women, all four have been ranked ahead of the U.S.A. by UN, the OECD, and a 2011 statistical study conducted by Lauren Streib for the U.S.A. publication Newsweek.But, do they recognize gay marriages?

If this marriage doesn't last, who is going to stay in your rental and make the payment?

sometimes the records are not correctly indexed, sometimes people's names are misspelled, (happened on a property that I bought where my name was misspelled), or people's names change through marriage, divorce, remarriage, junior, senior, other extensions  etc. 

Living in Texas though, common-law marriage is a very real possibility.

Their marriages, functions and their future family visits at least few times a year, we need good home equal to our current home level.

The relevant section of the lease in question states:If Tenant elects to voluntarily terminate this Lease during the initial Term (for example, house purchase, voluntary job change, marriage), two (2) full months' written notice prior to the rent due date to quit and vacate -- to run from the first of the month to the last day of the second month -- shall be given to Landlord.

Marriage bonds you legally to that of your spouse.
