Context paragraphs:
Li Shiji: Li Shiji (594 – December 31, 669), courtesy name Maogong, posthumously known as Duke Zhenwu of Ying, was a Chinese general who lived in the early Tang dynasty.  His original family name was Xú, but he was later given the family name of the Tang imperial clan, Li, by Emperor Gaozu, the Tang dynasty's founding emperor.  Later, during the reign of Emperor Gaozong, Li Shiji was known as Li Ji (i.e. the "Shi" in his name was omitted) to avoid naming taboo because the personal name of Emperor Gaozong's predecessor, Emperor Taizong (Li Shimin), had the same Chinese character "Shi".  Li Shiji is also referred to as Xu Maogong (his original family name and his courtesy name combined) in the historical novels "Shuo Tang" and "Sui Tang Yanyi".

Adin: Adin is an uncommon family name found today in England, the United States (particularly New York City), New Zealand, Sweden, the Basque country, Turkey and Israel.  Since the name occurs in the Old Testament, it has been suggested that the name has Jewish origins since it is mentioned in the Bible four times.  However, the Jewish Genealogical Society of Great Britain have no records of this as a Jewish family name.  The Consolidated Jewish Family Name Index of U.S.-based Avotaynu indicates Adin is a Jewish family name that existed in Poland and Belarus.  However this may be a phonetic coincidence since a name with so few letters might exist in every culture.

Cleomella brevipes: Cleomella brevipes is a species of flowering plant in the cleome family known by the common name shortstalk stinkweed.  It is native to the Mojave Desert and adjacent hills, where it grows in wet alkaline environments such as mineral-rich desert hot springs.  It is an annual herb producing a rough, waxy, red stem up to about 45 centimeters tall.  The stem is lined with many small fleshy leaves, each divided into three leaflets.  Flowers appear in the leaf axils all along the stem, often all the way down to the base.  Each grows at the end of a short, erect pedicel.  The flower has four tiny yellow sepals and four tiny yellow petals.  The fruit is a somewhat rounded, hanging capsule developing at the end of the remaining flower receptacle.

Slovak name: Slovak names consist of a given name and a family name (surname).  Slovakia uses the Western name order with the given name first and the surname last, although there is a tradition from the communist era to reverse this order in official administrative papers.  Most Slovaks do not have a middle name.  The family name forms for males and females are distinct in Slovakia, making it possible to identify gender from the name alone.  As of 2003 there were 185,288 different family names in use among 5.4 million Slovaks, or one family name for every 29 citizens.  There is an estimated 90,000 lineages in Slovakia.  With marriage, the bride typically adopts the bridegroom's surname.  Slovak names are very similar to Czech names.

Cleomella obtusifolia: Cleomella obtusifolia is a species of flowering plant in the cleome family known by the common name Mojave stinkweed.  It is native to the Mojave Desert and adjacent hills, where it grows in alkaline soils in the desert scrub.  It is an annual herb producing a rough, hairy stem up to 90 centimeters long.  The branching stem grows erect when new and then the branches droop to the ground with age, forming a bushy clump or mat.  Each leaf is made up of three fleshy oval leaflets.  Flowers appear in dense racemes on older stems and solitary in leaf axils on new stems.  Each flower has generally four hairy green sepals and four yellow petals grouped together on one side of the involucre.  The whiskery yellow stamens protrude up to 1.5 centimeters from the flower.  The fruit is a hairy, valved capsule a few millimeters in length.  It hangs at the tip of the remaining flower receptacle.

Galton–Watson process: The Galton–Watson process is a branching stochastic process arising from Francis Galton's statistical investigation of the extinction of family names.  The process models family names as patrilineal (passed from father to son), while offspring are randomly either male or female, and names become extinct if the family name line dies out (holders of the family name die without male descendants).  This is an accurate description of Y chromosome transmission in genetics, and the model is thus useful for understanding human Y-chromosome DNA haplogroups, and is also of use in understanding other processes (as described below); but its application to actual extinction of family names is fraught.  In practice, family names change for many other reasons, and dying out of name line is only one factor, as discussed in examples, below; the Galton–Watson process is thus of limited applicability in understanding actual family name distributions.

Scratchgravel Hills: The Scratchgravel Hills, el.  5233 ft are a small summit of hills northwest of Helena in Lewis and Clark County, Montana.  The area has seen increased development and a drop in water level in recent years.  The Scratchgravel Hills have alluvial deposits on top of faulted granitic bedrock.  There was extensive mining in the area in late 1800s through the 1930s.  The northern part of the region has folding shale, sandstone and limestone from the Algonkian (Belt) age.  Adjacent granite has altered them into quartz-mica schist and related rocks.  The southern and central portions of the region contains quartz monzonite.  Bitterroot and conifers are common in the area.

Bitterroot: Bitterroot ("Lewisia rediviva") is a small perennial herb in the Montiaceae family.

Sabaw: Sabaw is a Kachin family name.  This family name belongs to the Kachin that live in Kachin State in Burma.  They are originally from Sabaw Ga called Sabaw Land (Northern Burma).  The name originates from a certain group of people living in that land who were notably prosperous and rich with livestock.  From the name Sut baw (rich or prosperous) comes Sabaw.  They belong to the Hka Hku [one of the tribes from Kachin (Kachin State)] and a few others living in the surrounding area today.  Sabaw is Family Name and Amyu [the clan relationship name] is Udi Chyang Maja, Hkashu Hkasha.

Surname: A surname or family name is a name added to a given name.  In many cases, a surname is a family name and many dictionaries define "surname" as a synonym of "family name".  In the English-speaking world, it is commonly synonymous with last name because it is usually placed at the end of a person's full name, after any given names.
