Question:
The Tlingit language (English: , ; Tlingit: Lingit [linkit]) is spoken by the Tlingit people of Southeast Alaska and Western Canada. It is a branch of the Na-Dene language family. Extensive effort is being put into revitalization programs in Southeast Alaska to revive and preserve the Tlingit language and culture. Missionaries of the Russian Orthodox Church were the first to develop a written version of Tlingit, using the Cyrillic script to record and translate it, when the Russian Empire had contact with Alaska and the coast of North America down to Sonoma County, California.
Tlingit has eight vowels, four vowels further distinguished formally by length. However, the length distinction is often in terms of tenseness rather than length, particularly in rapid speech. For the Northern dialect, the dominant spoken dialect of Tlingit and the standard for written Tlingit, every vowel may take either high or low tone; in the orthography high tone is indicated by an acute accent, e.g. aa, and low tone is unmarked, e.g. aa. The Southern and Transitional dialects have a mid tone which is unmarked and additional low tone which is marked by a grave accent, e.g. aa. As noted in the vowel chart above, there is an allophone of /a:/ (orthographic aa) which is realized as [a:] under the influence of uvular consonants, however this is not consistent for all speakers. The backness influence arises from articulation with uvular consonants, thus the word khaa "person" is often spoken as [qha:], whereas the word (a) kaa "on (its) surface" is said as [(?^) kha:] by the same speakers. Word onset is always consonantal in Tlingit, i.e. no word may begin with a vowel. Where one would occur theoretically by e.g. prefixing or compounding, the vowel is obligatorily preceded by either [?] or [j]. The former is universal in single words, and the latter is found varying with [?] in word-medial position in compounds. The orthography does not reflect the [?] in word-initial position, but either . or y may be seen in medial position. For example, the word khoowat'aa "the weather is hot" (khu-yu-ya-t'aa, INDH.OBJ-PERF-(0, -D, +I)-hot) is phonetically [qhu:w^t'a:], but when the perfective prefix yu- is word initial in uwat'aa "it is hot" (0-yu-ya-t'aa, 3NEU.OBJ-PERF-(0, -D, +I)-hot) the phonetic form is [?Uw^t'a:] where the glottal stop appears to ensure that the word begins with a consonant.

Answer the question at the end by quoting:

O'Neill was born in a hotel, the Barrett House, at Broadway and 43rd Street, on what was then Longacre Square (now Times Square). A commemorative plaque was first dedicated there in 1957. The site is now occupied by 1500 Broadway, which houses offices, retail, and ABC Studios. He was the son of Irish immigrant actor James O'Neill and Mary Ellen Quinlan, who was also of Irish descent.
O'Neill was married to Kathleen Jenkins from October 2, 1909 to 1912, during which time they had one son, Eugene O'Neill, Jr. (1910-1950). In 1917, O'Neill met Agnes Boulton, a successful writer of commercial fiction, and they married on April 12, 1918. They lived in a home owned by her parents in Point Pleasant, New Jersey, after their marriage. The years of their marriage--during which the couple lived in Connecticut and Bermuda and had two children, Shane and Oona--are described vividly in her 1958 memoir Part of a Long Story. They divorced in 1929, after O'Neill abandoned Boulton and the children for the actress Carlotta Monterey (born San Francisco, California, December 28, 1888; died Westwood, New Jersey, November 18, 1970). O'Neill and Carlotta married less than a month after he officially divorced his previous wife. In 1929, O'Neill and Monterey moved to the Loire Valley in central France, where they lived in the Chateau du Plessis in Saint-Antoine-du-Rocher, Indre-et-Loire. During the early 1930s they returned to the United States and lived in Sea Island, Georgia, at a house called Casa Genotta. He moved to Danville, California in 1937 and lived there until 1944. His house there, Tao House, is today the Eugene O'Neill National Historic Site. In their first years together, Monterey organized O'Neill's life, enabling him to devote himself to writing. She later became addicted to potassium bromide, and the marriage deteriorated, resulting in a number of separations, although they never divorced. In 1943, O'Neill disowned his daughter Oona for marrying the English actor, director, and producer Charlie Chaplin when she was 18 and Chaplin was 54. He never saw Oona again. He also had distant relationships with his sons. Eugene O'Neill, Jr., a Yale classicist, suffered from alcoholism and committed suicide in 1950 at the age of 40. Shane O'Neill became a heroin addict and moved into the family home in Bermuda, Spithead, with his new wife, where he supported himself by selling off the furnishings. He was disowned by his father before also committing suicide (by jumping out of a window) a number of years later. Oona ultimately inherited Spithead and the connected estate (subsequently known as the Chaplin Estate). In 1950 O'Neill joined The Lambs, the famed theater club.
