Ogden Syndrome: Ogden Syndrome, also known as n-terminal acetyltransferase deficiency (NATD), is an x-linked disorder of infancy comprising a distinct combination of distinctive craniofacial features producing an aged appearance, growth failure, hypotonia, global developmental delays, cryptorchidism, and acquired cardiac arrhythmias.  The first family was identified in Ogden, Utah, with five affected boys in two generations of family members.  A mutation was identified as a c.109T>C (p.Ser37Pro) variant in NAA10, a gene encoding the protein Naa10 catalytic subunit of the major human N-terminal acetyltransferase (NatA).  This same mutation was identified in a second unrelated family, with three affected boys in two generations.  This X-linked Malformation and Infantile Lethality Syndrome has provisionally been named Ogden Syndrome, in honor of the hometown where the first family resides.

English Springer Spaniel: The English Springer Spaniel is a breed of gun dog in the Spaniel family traditionally used for flushing and retrieving game.  It is an affectionate, excitable breed with a typical lifespan of twelve to fourteen years.  They are very similar to the Welsh Springer Spaniel and are descended from the Norfolk or Shropshire Spaniels of the mid-19th century; the breed has diverged into separate show and working lines.  The breed suffers from average health complaints.  The show-bred version of the breed has been linked to "rage syndrome", although the disorder is very rare.  It is closely related to the Welsh Springer Spaniel and very closely to the English Cocker Spaniel; less than a century ago, springers and cockers would come from the same litter.  The smaller "cockers" hunted woodcock while the larger littermates were used to flush, or "spring," game.  In 1902, The Kennel Club recognized the English Springer Spaniel as a distinct breed.  They are used as sniffer dogs on a widespread basis.  The term "Springer" comes from the historic hunting role, where the dog would flush (spring) birds into the air.

Buddy (dog): Buddy (August 7, 1997 – January 2, 2002), a male chocolate-colored Labrador Retriever, was one of two pets kept by the Clinton family while Bill Clinton was President of the United States.  The Clintons' other pet was a cat named Socks.

Bo (dog): Bo (born October 9, 2008) is a pet dog of the Obama family, the former First Family of the United States.  Bo is a male Portuguese Water Dog.  President Barack Obama and his family were given the dog as a gift after months of speculation about the breed and identity of their future pet.  The final choice was made in part because Malia Obama's allergies dictated a need for a hypoallergenic breed.  Bo has occasionally been called "First Dog".  In August 2013, Bo was joined by Sunny, a female dog of the same breed.

Sunny (dog): Sunny (born June 11, 2012) is a pet dog of the Obama family, the former First Family of the United States.  Sunny is a female Portuguese Water Dog, who has been called the younger sister of Bo, who held the title of First Dog of the United States.  Sunny was introduced via First Lady Michelle Obama's Twitter account on August 19, 2013.

Rat Terrier: The Rat Terrier is an American dog breed with a background as a farm dog and hunting companion.  Traditionally more of a type than a breed, they share much ancestry with the small hunting dogs known as feists. Common throughout family farms in the 1920s and 1930s, they are now recognized by the United and American Kennel Clubs and are considered a rare breed.  Today's Rat Terrier is an intelligent and active small dog that is kept both for pest control and as a family pet.

British Milk (sheep): The British Milksheep originally was known as the Alderbred and is a breed of domesticated sheep developed by Lawrence Alderson in Wiltshire and Northumberland.  It was exported to several countries including Hungary, France and Greece, and from there other neighbouring countries.  It now can be found mainly in the UK, Hungary and Canada, although the population in Britain was decimated during the outbreak of foot-and-mouth disease in 2001.  The exact composition of the breed has never been declared but it was based on high-performance animals in existing flocks of Dorset Horn, Bluefaced Leicester and Eastrip Prolific sheep kept by the Alderson family.  Additional individual animals were selected from Lleyn, Texel and East Friesian breeds.  Subsequent selection was based on measures of productivity, without regard for uniformity of appearance.  A standardised breed type emerged gradually as the blending process continued.  The animals were exposed to rugged conditions in the upper Pennines in northern England to develop robustness and adaptability.  Progeny testing from the initial stages laid the foundation for continuous genetic improvement.  Initially, total ownership of females of the breed was retained by the family and only rams were sold, but groups of females were released to other breeders in 1981.  Numbers of flocks and animals increased rapidly and there were more than 5,000 breeding ewes by the mid-1980s with flocks widespread in Britain.  A flock book was published in 1986.  As the name of the breed suggests, it is a prolific milk producer, and several large dairy flocks were established.  However, it is a robust, general-purpose sheep rather than a specialist dairy breed.  It is known for its extremely high prolificacy, and rams are used to sire high-performance crossbred daughters.  The quality of its carcase and wool are extra beneficial traits.  In all countries outside Britain, the British Milksheep is used more as a dairying breed with dual-purpose qualities, but it is used also in most countries as a crossing sire; in Britain on hill and longwool breeds, in France in the Alps and Pyrenees on mountain breeds, in Greece on Chios dairy ewes, and in Hungary on the predominant Merino population.  In France it has contributed to the development of the Boulonnais breed.

Socks (cat): Socks Clinton (Spring 1989 – February 20, 2009) was the pet cat of U.S. President Bill Clinton's family during his presidency.  As an adopted stray cat, he was the only pet of the Clintons during the early years of the administration, and his likeness hosted the children's version of the White House website.  After Clinton left office, Socks resided with former Clinton secretary Betty Currie and her husband, owing to continuing conflicts with Clinton's dog Buddy.

First Families of Pakistan: The First Family is an unofficial title for the family of the head of state or head of government of a country (usually a republic).
