The wife of Robert Owen, founder of the New Harmony community in Indiana, was (Ann) Caroline or Carolina Dale, a known descendant of John Campbell, d. 1777, "cashier" of the Bank of Scotland. Robert Owen and Caroline Dale have a good number of prominent American descendants: https://en.wikipedia.org/wiki/David_Dale_Owen https://en.wikipedia.org/wiki/Caroline_Dale_Snedeker https://en.wikipedia.org/wiki/Robert_Dale_Owen https://en.wikipedia.org/wiki/Richard_Owen_(geologist) https://faculty.evansville.edu/ck6/bstud/jdowen.html https://en.wikipedia.org/wiki/Constance_Faunt_Le_Roy_Runcie Ann Caroline (Dale) Owen's line of descent from John Campbell was: John Campbell, d. 1777 = (2) Ann Carolina Campbell "of Tofts" Ann Carolina Campbell = David Dale Ann Carolina/Caroline Dale = Robert Owen, sometime of New Harmony, Indiana See: https://www.rbs.com/heritage/people/david-dale.html https://www.rbs.com/heritage/people/john-campbell.html The opening paragraph of "cashier" John Campbell's biography in the _Oxford Dictionary of National Biography_ says: "Campbell, John (c.1703–1777), banker and businessman, was held by contemporaries to be an illegitimate son of Colin Campbell of Ardmaddy, younger son of the first earl of Breadalbane (1634–1717). Later testimonies suggest that Colin Campbell married Grizel Douglas against the earl's wishes, and that all evidence of this legal marriage was later destroyed, and with it, the claim of John Campbell's descendants to the earldom. After his father's death, John was raised in the Breadalbane household at Finlarig in the Perthshire highlands. In 1718 he was apprenticed to Colin Kirk, writer to the signet, for three years." Some very accurate information on Cashier John's supposed father, Colin (? of Armaddy), appears in _6 Papers Relating To Claims To The Earldom Of Breadalbane and Holland_, published in 1866. John Campbell, first earl of Breadalbane, registered a deed in a minor court in Edinburgh in July 1705--it did not make its way into the books of Council and Session and the General Register House until 1870. In this deed, Breadalbane mentioned his older son Lord Glenorchy, and Glenorchy's lawful heirs-male, "which failing ... to Master Colin Campbell, also his the said John first Earl of Breadalbane's lawful son procreate between him and Mary Countess of Caithness, his last spouse, and the heirs male of his body ..." The fuller history of Colin Campbell is given in the commentary following this deed: "The said Master Colin Campbell, the son of the first Earl by his spouse Mary Countess of Caithness, died on the 31st day of March 1708, at Kensington, in the county of Middlesex [England], and a tablet to his memory is in the church of that parish. There is contained under the date of the year 1710, in the Kirk Session Register in the parish of Kenmore, in which parish Taymouth Castle is situate, a copy of a letter, dated March 16th, 1710, from the first Earl to his chamberlain, John Campbell, which commences as follows: --- 'Whereas it pleased God to remove my son, Master Colin Campbell, at London, the last day of March 1708. He did by his latter will mortifie and bequeath an hundred pounds sterline in money, chargeable on his estate in Nether Lorne, and the annual rent thereof, to be yearly paid by our order, and our successor's direction and the minister and kirk session of Kenmor, to the said minister and kirk session of that parish.' No will of the said Colin Campbell is registered or to be found recorded in Scotland or England." https://books.google.com/books?id=ydANAAAAQAAJ&pg=RA2-PA7&dq=%22failing+to+master+colin+campbell%22&hl=en&sa=X&ved=0ahUKEwjfq4yo6JPWAhUGziYKHZhyB7QQ6AEIKDAA#v=onepage&q=%22failing%20to%20master%20colin%20campbell%22&f=false This document and the sources it quotes shows that John, 1st earl of Breadalbane, had a lawful son, Mr. or "Master" Colin Campbell,--i.e., a minister (or at least a university graduate). Mr. Colin died 31 March 1708 and is buried at Kensington in England, with the following inscription: Here lyeth the body of Mr. Colin Campbell, son to the Earl of Bread Albany and Holland, and to Mary, Countess Dowager of Caithness, daughter of Archibald [Campbell], Marquis of Argyle. He died the 31st day of March, in the year 1708, and of his age the 29th year. A youth of great parts and hopes.
