Power of attorney ends when the principal dies. If the principal has a will, the will allocates authority and assets subject to community property and statutory share laws. If the principal has no will state intestate succession laws govern and the wife likely has major power and right to assets.

Agent's power under DPOA terminates at death of principal. Now the issue is whether decedent had a Will. Also open is whether or not a common law marriage was in fact established in Kansas. Assuming there is a valid common law marriage, there will be community property verses separate property issues to resolve. An attorney is needed.
As death was in Texas, Texas has jurisdiction, unless the decedent had no intention to make Texas his domicile and you can prove this. If, however, nothing was owned in Texas and there is real estate in Kansas, then Kansas has at least jurisdiciton over the real estate. Texas presumes another state's law is the same asthe law of Texas; thus the court will assume the common law claim from Kansas should be proved up the same as a Texas common law.
As stated by lawyers below, the Power of Attorney has no power. However, if you can identify that the power of attorney was signed in an attorney's office, that attorney may have prepared a Will.
