A married name is the family name adopted by a person upon marriage. When a person assumes the family name of his or her spouse, this name replaces the person's original family name, which then becomes a maiden name.

The term "maiden name" is rarely applied to the change of family names by men, or by either sex other than in connection with marriage. Nevertheless, the French and English-adopted term "née" ( /ˈneɪ/ or  /ˈniː/; French: [ˈne]), meaning "born as," can be applied to a woman's family name at birth that has been replaced for any reason. The French masculine inflection corresponding to née is "né"; while less readily recognized by non-French-speakers, it is likewise applied to family names changed for any reason. (The diacritics are sometimes omitted.)

The term "birth name" is sometimes used specifically as a gender-neutral (or male only) substitute for "maiden name", but it is also applied to mean the family name of the mother of a child adopted at birth, and is thus likely to be used with more flexibility than the loan-words née and né, accepting it even when the name being referred to was acquired by adoption (at or long after birth), or made in connection with a change of nationality, or changed in any of the variety of other, rarer circumstances.

Donald Brian "Buck Dharma" Roeser (born November 12, 1947, On Long Island, New York) is an American guitarist and songwriter, best known for being a member of Blue Öyster Cult since the group's formation in 1967. He wrote and sang the lead vocal on many of the band's best-known hits, including "(Don't Fear) The Reaper", "Godzilla", and "Burnin' for You" (the last originally intended for Roeser's solo album.)

The nickname came from an idea from the band's manager, Sandy Pearlman, who envisioned each member of the band having an unusual stage name; Roeser was the only one who took to the idea, and his was the only name that stuck.

Roeser is notable for his use of the Gibson SG and numerous custom Steinberger models. One of his Steinberger guitars has a body carved to look like Swiss cheese (see photo). Dharma calls this guitar his "Cheeseberger".

His other equipment use includes: a Giuliano Balestra Vulcan, a Fender Stratocaster, a St. Blues and custom models built by Rick Kresiak, Harper Guitars and Warren Guitars. Many of his guitars were made by White Plains based custom guitar maker, Guliano.
