She succeeded her sister-in-law Inger Oxe, who held the office from 1572 to 1584, as Chief Lady-in-Waiting to Queen Sophie.  Beate Bille was the mother of astronomer Tycho Brahe.

Tycho Brahe: Tycho Brahe ( , born Tyge Ottesen Brahe (] ); 14 December 154624 October 1601) was a Danish nobleman known for his accurate and comprehensive astronomical and planetary observations.  He was born in the then Danish peninsula of Scania.

Singh: Singh is a title, middle name or surname, which originated in India.  Derived from the Sanskrit word for lion, it was adopted as a title by certain warrior castes in India.  It was mandated by Guru Gobind Singh for all Sikhs.  It was later adopted by several castes and communities.  As a surname or a middle name, it is now found throughout the Indian subcontinent and among the Indian diaspora, cutting across communities and religious groups, becoming more of a title than a surname.

Latvian name: Latvian names, like in most European cultures, consist of two main elements: the given name ("vārds") followed by family name ("uzvārds").  During the Soviet occupation (1940 - 1991) the practice of giving a middle name was discouraged, but since the restoration of Independence Latvian legislation again allows giving of up to two given names and it has become more common to give a middle name to children.

Middle name: In several cultures, people's names usually include one or more names in addition to the portion that is usually considered adequate to identify them.  In a number of cultures where a given name is expected to precede the surname, such a name is likely to be placed after the given name and before the surname, and thus called a middle name.  In English-speaking American culture, that term is often applied (arguably mistakenly) to names, occupying that position, even if the bearer would insist that that name is being mistakenly called a "middle name", and is actually (to mention several types of atypical cases):

Marion Christopher Barry: Marion Christopher Barry was born in June 1980 to Marion Barry and Barry's third wife, Effi Slaughter Barry.  He was their only child.  His father had wanted to name him Marion Barry III, but Effi was strongly opposed, and they decided to give him the middle name Christopher instead.  For most of his adult life, Barry went by his middle name, Christopher.
