Matthew Boulton  (; 3 September 1728 - 17 August 1809) was an English manufacturer and business partner of Scottish engineer James Watt. In the final quarter of the 18th century, the partnership installed hundreds of Boulton & Watt steam engines, which were a great advance on the state of the art, making possible the mechanisation of factories and mills. Boulton applied modern techniques to the minting of coins, striking millions of pieces for Britain and other countries, and supplying the Royal Mint with up-to-date equipment.
The elder Boulton's business prospered after young Matthew's birth, and the family moved to the Snow Hill area of Birmingham, then a well-to-do neighbourhood of new houses. As the local grammar school was in disrepair Boulton was sent to an academy in Deritend, on the other side of Birmingham. At the age of 15 he left school, and by 17 he had invented a technique for inlaying enamels in buckles that proved so popular that the buckles were exported to France, then reimported to Britain and billed as the latest French developments.  On 3 March 1749 Boulton married Mary Robinson, a distant cousin and the daughter of a successful mercer, and wealthy in her own right. They lived briefly with the bride's mother in Lichfield, and then moved to Birmingham, where the elder Matthew Boulton made his son a partner at the age of 21. Though the son signed business letters "from father and self", by the mid-1750s he was effectively running the business. The elder Boulton retired in 1757 and died in 1759.  The Boultons had three daughters in the early 1750s, but all died in infancy. Mary Boulton's health deteriorated, and she died in August 1759. Not long after her death Boulton began to woo her sister Anne. Marriage with a deceased wife's sister was forbidden by ecclesiastical law, though permitted by common law. Nonetheless, they married on 25 June 1760 at St. Mary's Church, Rotherhithe. Eric Delieb, who wrote a book on Boulton's silver, with a biographical sketch, suggests that the marriage celebrant, Rev. James Penfold, an impoverished curate, was probably bribed. Boulton later advised another man who was seeking to wed his late wife's sister: "I advise you to say nothing of your intentions but to go quickly and snugly to Scotland or some obscure corner of London, suppose Wapping, and there take lodgings to make yourself a parishioner. When the month is expired and the Law fulfilled, live and be happy ... I recommend silence, secrecy, and Scotland."  The union was opposed by Anne's brother Luke, who feared Boulton would control (and possibly dissipate) much of the Robinson family fortune. In 1764 Luke Robinson died, and his estate passed to his sister Anne and thus into Matthew Boulton's control.  The Boultons had two children, Matthew Robinson Boulton and Anne Boulton. Matthew Robinson in turn had six children with two wives. His eldest son Matthew Piers Watt Boulton, broadly educated and also a man of science, gained some fame posthumously for his invention of the important aeronautical flight control, the aileron. As his father before him, he also had two wives and six children.

Did he ever start a family of his own?

Boulton married Mary Robinson, a distant cousin and the daughter of a successful mercer, and wealthy in her own right.

George Michael Cohan (July 3, 1878 - November 5, 1942), known professionally as George M. Cohan, was an American entertainer, playwright, composer, lyricist, actor, singer, dancer and producer. Cohan began his career as a child, performing with his parents and sister in a vaudeville act known as "The Four Cohans." Beginning with Little Johnny Jones in 1904, he wrote, composed, produced, and appeared in more than three dozen Broadway musicals. Cohan published more than 300 songs during his lifetime, including the standards "Over There", "Give My Regards to Broadway", "The Yankee Doodle Boy" and "You're a Grand Old Flag".
Cohan appeared in 1930 in a revival of his tribute to vaudeville and his father, The Song and Dance Man. In 1932, Cohan starred in a dual role as a cold, corrupt politician and his charming, idealistic campaign double in the Hollywood musical film The Phantom President. The film co-starred Claudette Colbert and Jimmy Durante, with songs by Rodgers and Hart, and was released by Paramount Pictures. He appeared in some earlier silent films but he disliked Hollywood production methods and only made one other sound film, Gambling (1934), based on his own 1929 play and shot in New York City. A critic called Gambling a "stodgy adaptation of a definitely dated play directed in obsolete theatrical technique." It is considered a lost film.  Cohan earned acclaim as a serious actor in Eugene O'Neill's only comedy, Ah, Wilderness! (1933), and in the role of a song-and-dance President Franklin D. Roosevelt in Rodgers and Hart's musical I'd Rather Be Right (1937). The same year, he reunited with Harris to produce a play called Fulton of Oak Falls, starring Cohan. His final play, The Return of the Vagabond (1940), featured a young Celeste Holm in the cast.  In 1940, Judy Garland played the title role in a film version of his 1922 musical Little Nellie Kelly. Cohan's mystery play Seven Keys to Baldpate was first filmed in 1916 and has been remade seven times, most recently as House of Long Shadows (1983), starring Vincent Price. In 1942, a musical biopic of Cohan, Yankee Doodle Dandy, was released, and James Cagney's performance in the title role earned the Best Actor Academy Award. The film was privately screened for Cohan as he battled the last stages of abdominal cancer; Cohan's comment on Cagney's performance was, "My God, what an act to follow!" Cohan's 1920 play The Meanest Man in the World was filmed in 1943 with Jack Benny.
