Agnatic seniorityAgnatic seniority is a patrilineal principle of inheritance where the order of succession to the throne prefers the monarch's younger brother over the monarch's own sons. A monarch's children (the next generation) succeed only after the males of the elder generation have all been exhausted. Agnatic seniority essentially excludes females of the dynasty and their descendants from the succession. Contrast agnatic primogeniture, where the king's sons stand higher in succession than his brothers.
Y-chromosomal AdamIn human genetics, the Y-chromosomal most recent common ancestor (Y-MRCA, informally known as Y-chromosomal Adam) is the patrilineal most recent common ancestor (MRCA) from whom all currently living humans are descended. He is the most recent male from whom all living humans are descended through an unbroken line of their male ancestors. The term Y-MRCA reflects the fact that the Y chromosomes of all currently living human males are directly derived from the Y chromosome of this remote ancestor.
IsraelitesThe Israelites (ˈɪzrəlaɪts,_-riə-; , Bənēy Yīsrāʾēl, ) were a group of Semitic-speaking tribes in the ancient Near East who, during the Iron Age, inhabited a part of Canaan. The earliest recorded evidence of a people by the name of Israel appears in the Merneptah Stele of ancient Egypt, dated to about 1200 BCE. According to the modern archaeological account, the Israelites and their culture branched out of the Canaanite peoples and their cultures through the development of a distinct monolatristic—and later monotheistic—religion centred on the national god Yahweh.
SurnameA surname, family name, or last name is the mostly hereditary portion of one's personal name that indicates one's family. It is typically combined with a given name to form the full name of a person. Depending on culture, the surname may be placed at either the start of a person's name, or at the end. The number of surnames given to an individual also varies: in most cases it's just one, but in many Spanish-speaking countries, two surnames are used for legal purposes.
SamaritansSamaritans (səˈmærɪtənz; ; שומרונים; السامريون) are an ethnoreligious group who originate from the ancient Israelites. They are native to the Levant and adhere to Samaritanism, an Abrahamic and ethnic religion similar to Judaism, but differing in several important aspects. Samaritan tradition claims the group descends from the northern Israelite tribes who were not deported by the Neo-Assyrian Empire after the destruction of the Kingdom of Israel.
Genetic genealogyGenetic genealogy is the use of genealogical DNA tests, i.e., DNA profiling and DNA testing, in combination with traditional genealogical methods, to infer genetic relationships between individuals. This application of genetics came to be used by family historians in the 21st century, as DNA tests became affordable. The tests have been promoted by amateur groups, such as surname study groups or regional genealogical groups, as well as research projects such as the Genographic Project. about 30 million people had been tested.
Hereditary titleHereditary titles, in a general sense, are nobility titles, positions or styles that are hereditary and thus tend or are bound to remain in particular families. Though both monarchs and nobles usually inherit their titles, the mechanisms often differ, even in the same country. The British crown has been heritable by women since the medieval era (in the absence of brothers), while the vast majority of hereditary noble titles granted by British sovereigns are not heritable by daughters.
