If you are writing to a widow whose last name is different from her husband's, you should use the title "Ms." with her name ("Ms. Brown," not "Mrs. Brown"). Even though she may use a different name from her husband's, it is unlikely that she would be upset if you used her husband's name ("Mrs. Smith" instead of "Ms. Brown"). After all, that name connects her to the man whose loss she is grieving, so she might like it.
On a legal document she should sign her name as Jane Doe, or Jane Schmoh Doe (if her maiden name is Schmoh). If she wants sign personal letters Mrs. John Doe to stress the connection to her late husband, that is her choice.
When addressing an envelope to a husband and wife it should be: Mr. & Mrs. John Doe. If either of the partners are a doctor, etc., then it would read Dr. & Mrs. John Doe or Pastor & Mrs. John Doe, etc.

Commonly the wife used to take the name of her husband. For a few years now it is permitted to add the wife's maiden name to the name of her husband (Miss Durant marrying mr. Dupont could be called mrs Dupont-Durant, and her children too) or even to retain her original maiden name. The usual way is still to take the husband's family name.
