The Edmund and Mary Ann Walworth Booth House is a historic building located in Anamosa, Iowa, United States.
 Raised in Longmeadow, Massachusetts, Edmund Booth contracted meningitis at age four and lost part of his hearing.
 By the time he was eight he was totally deaf.
 His wife Mary Ann was born in Connecticut and she was also four when she contracted meningitis, but lost all of her hearing at that time.
 Booth became an early educator for the deaf, and his wife was one of his pupils.
 They both relocated separately to Iowa in 1839, and married the following year.
 After spending five years in the California gold fields while his family remained in Iowa, Booth returned to Iowa and resumed farming.
 He was instrumental in establishing the Iowa School for the Deaf in 1855, and the Iowa Association of the Deaf in 1881.
 He became the association's president in 1884.
 Booth had a thirty-year career as the publisher and editor of the "Anamosa Eureka".
 The Booth's had this brick Italianate house built in 1870.
 They lived here until Mary Ann died in 1898 and Edmund in 1905.
 It was listed on the National Register of Historic Places in 2001.
The Sainsbury family (also Lord Sainsbury and family and incorrectly the Sainsbury's family) founded Sainsbury's, the UK's second-largest supermarket chain.
 Today, the family has many interests, including business, politics, philanthropy, arts, and sciences.
Sainsbury's is the second largest chain of supermarkets in the United Kingdom, with a 16.9% share of the supermarket sector in the United Kingdom.
 Founded in 1869, by John James Sainsbury with a shop in Drury Lane, London, the company became the largest grocery retailer in 1922, was an early adopter of self-service retailing in the United Kingdom, and had its heyday during the 1980s.
 In 1995, Tesco overtook Sainsbury's to become the market leader, and Asda became the second largest in 2003, demoting Sainsbury's to third place for most of the subsequent period until January 2014, when Sainsbury's regained second place.

Mary Ann M'Clintock is best known for her role in the formation of the women's suffrage movement, as well as abolitionism.
 She was married to Thomas M'Clintock and they were both invested in their Quaker backgrounds, and social reform.
 Thomas provided for their four daughters and their son by working as a druggist and minister.
 From the beginning of their marriage in 1820 the lived in Philadelphia until 1836 when they moved to Waterloo, NY.
 By 1833 Marry Ann was very active in the anti-slavery movements in Philadelphia and was one of the founding members of the anti-slavery society.
 She worked closely with abolitionist Lucretia Mott.
 Once moved to Waterloo, Mary Ann took a more active role in the women's suffragist movement.
 Mary Ann had a hand in organizing the Seneca Falls Convention, held in July 1848.
 She and her daughters Elizabeth and Mary Ann also attended the convention and signed the declaration of sentiments.
 The base of the convention was to present the Declaration of Sentiments, this document drafted by women such as Elizabeth Cady Stanton and Lucretia Mott at the kitchen table of Mary Ann M'Clintock and outlines equal opportunities among men and women.
 The Declaration of Sentiments was modeled after the Declaration of Independence and was the fuel that started the fire that was the suffragist movement which lasted until 1920.
 However, Mary Ann never got to vote.
 In 1856 She retired back to Philadelphia and died in 1884 at the age of 84.
Michael J. Cullen (1884–1936) was an American entrepreneur and salesman of Irish descent, perhaps best known as the founder of the King Kullen grocery store chain, widely considered to be the first supermarket founded in America.

Mary Ann Sainsbury ("née" Staples; 30 June 1849 - 9 June 1927) was the wife of John James Sainsbury, the founder of the Sainsbury's supermarket chain.
"Génesis" is the name given to the third studio album by the Puerto Rican singer, songwriter and actress, Mary Ann Acevedo, released in January 1, 2012 worldwide through digital download and in December 7, 2012 on compact disc.
 Originally the album was confirmed for release in February 2010 as "El Amor es la Solución", but with the birth of her daughter, Mary Ann had to delay the departure of the album to April 2010; then GT Musik announced the album release was delayed for a few months.
 She agreed that her homonymous first album was a continuation of her tenure in the third edition of "Objetivo Fama".
 On that album, the songs were chosen when Mary Ann left the reality show; in December she was released a special production titled "Cántale a tu Bebé".
