As Martha Washington began her new life with George she must have been hoping as she said her wedding vows that she would have more of "better" and less of the "for whose". Missing from the ceremonies were her father and brother John, sister Frances and two of her children--all of these people had died in the decade preceding her marriage to George plus she was a widow of less than two years.
In a letter Martha wrote to a friend later in her life she said: "I am still determined to be cheerful and happy, in whatever situation I may be; for I have also learned from experience that the greater part of our happiness or misery depends upon our dispositions, not upon our circumstances." (Letter, Martha Washington to Mercy Otis Warren, 12/16/1789).
I think, to a large extent, this attitude helped Martha through the really rough patches in her life
