Michelle Phillips (born Holly Michelle Gilliam; June 4, 1944) is an American singer, songwriter and actress.
 A native of California, she met and married John Phillips in San Francisco as a teenager, and went on to co-found the vocal group The Mamas & the Papas in 1965.
 The band rose to fame with their popular singles "California Dreamin'" and "Creeque Alley", both of which Phillips co-wrote.
 They released five studio albums before their dissolution in 1970.
 Phillips is the last surviving original member of the group.
This is a list of notable people who have changed, adopted or adjusted their surnames based on a mother's or grandmother's maiden name.
 Included are people who changed their legal names and people who created personal or professional pseudonyms. Under longstanding Western custom and law, children are customarily given the father's surname, except for children born outside marriage, who often carry their mother's family names.
 However, in the 1970s, some women began to adopt their mother's maiden name as their legal surnames.
 People in Sweden have recently begun adopting maternal line surnames in an effort to broaden the number of last names in the country.
The California Birth Index (CABI) is a database compiled by the California Office of Health Information and Research.
 The index contains birth records of all registered births in California between 1905 and 1995.
 Each record is an abstract of a person's birth certificate, including date of birth, full name, county of birth, gender, and mother's maiden name.
 People who have been adopted are sometimes listed by their birth name, sometimes listed by their adopted name, sometimes by both and sometimes not listed at all.
 The CABI is considered a valuable genealogy tool but is also criticized for privacy issues.
 California began statewide civil registration of births on July 1, 1905.
 Earlier birth records may exist in the county where the birth took place or at the church where a baptism took place.

When a person (traditionally the wife in many cultures) assumes the family name of his or her spouse, that name replaces the person's birth surname, which in the case of the wife is called the maiden name (birth name is also used as a gender-neutral or masculine substitute for maiden name), whereas a married name is a family name or surname adopted by a person upon marriage.
