"The Hagey Families in America and the Dulaney Family" by King Albert Hagey published in 1951
Her death date and age of death are listed in her son-in-law's bible. Her birth date was calculated from this data. Information was extracted from the Isaac Mumma and Mary Nissley family bible which can be viewed at

Chas Fies records lists Mary's first husband, John Detweiler, as being buried in the Ruth/Detweiler/Martin Farm Cemetery in 1833. There is also a notice in 1888 that this cemetery is neglected and will be abandoned and grave markers removed. It is questionable that the body would have been moved.
Her son, Samuel Detweiler is buried in Middletown Cemetery, Middletown, Dauphin Co., PA. His tombstone lists his father and mother's name and their dates of birth and death but I do not know if they are actually buried there as the cemetery does not have a record and it was apparently customary to lists parents names at that time on the tombstone.
There is no other record for Mary Heagy Detweiler Mumma than the inscription on Samuel's tombstone which lists her only under John Detweiler's name as "Mary his wife, 1804-1851."
