Mayflower Descendant 13th Generation

My mother is a 13th generation descendant. The primary documents that I can submit for her are:

1. Certificate of Death. The primary evidence is the name, date, time, location, cause of death, burial location, name of physician that pronounced death, social security number. The secondary information provided by her spouse (my father). This includes her date and location of birth, occupation and place of employment, name of parents. Other evidence that lists children, grandchildren and names of siblings and spouse include the obituary that ran in the local paper and the copy of the funeral mass and copies of the eulogies given by her daughters and husband. The Social Security Death Index that may be accessed publicly on line has her name, birth month and year, death month and year, state where social security number issued, county and state where last benefit was paid and the social security number. A copy of the original application may be ordered for a fee from the SSA under the Freedom of Information Act.
2. Marriage certificate. Both the town and state have copies of the marriage certificate. It was less expensive and less time consuming to obtain this document from the town office. The primary evidence on this document is the names and address at time of application for license of both the bride and groom, their date and location at time of marriage. Of less genealogy value is the birth date and location of the bride and groom. In addition to this source there is the Marriage certificate issued by the priest that performed the marriage along with the names, dates and location of the bride and groom and the witnesses. The local paper ran an announcement of the marriage that listed the bride, groom, parents of bride and groom, names of the wedding party, date and location of the wedding. There are also numerous photos that have in my mothers handwriting the names of the people that are in the photos.
3. 1930 US Federal Census. This lists her relationship to the head of household, age, location at the time the census was taken.
4. Birth Certificate. The state issued certificate gives the date, location, and name of child born. The names of the parents, where they lived at time of birth, the occupation of the mother and father, their age at their last birthday and location of birth. The certificate is signed by the attending physician.

The Mayflower Society also requests the birth certificate of my father even though he is not a Mayflower descendant.
