Family took over brewery operations. On 17 June 1761, Guinness married Olivia Whitmore, a younger woman from a wealthy and well-connected family who offered him a £1,000
dowry. Whitmore was a descendant of
William of Wykeham and had several socio-politically prominent relatives. One of these was her cousin
Henry Grattan, a member of the
Parliament of Ireland who argued in favour of aiding Catholics and gaining legislative independence in Ireland. With Arthur, Olivia Guinness suffered 11
miscarriages but gave birth to ten children, all but one of whom, Olivia, survived into adulthood. These four daughters and six sons were named, from oldest to youngest, Elizabeth, Hosea, Arthur, Edward, Olivia, Benjamin, Louisa, John Grattan, William Lunell, and Mary Anne. Elizabeth was born on 28 February 1763; by the time of Mary Anne's birth in 1787, Elizabeth was already married. Elizabeth Guinness married Frederick Darley in 1809, the same year that he became the
Lord Mayor of Dublin. As Guinness's firstborn son, Hosea, born in 1765, was expected to inherit the family business, but he instead chose to enter the clergy. He was educated at
Winchester College, the
University of Oxford, and Trinity College Dublin before serving as the
rector of
St. Werburgh's Church, Dublin, until his death in 1841. Both Louisa and Mary Anne married into the clergy, wedding William Dean Hoare and John Burke, respectively. Guinness's third child,
also named Arthur, was born in 1768. Upon his father's death, he inherited the brewery at St. James's Gate, where he was assisted by his brothers Benjamin and William. In 1808, Benjamin and William became full partners in the company, which was renamed Guinness (A., Ben & W.L.) brewers. John Grattan Guinness, who had previously served in the
East India Company, joined the brewery company as a sales agent in 1824, but left the position after his wife's death. When the younger Arthur died himself in 1855, his youngest son, named Benjamin after his uncle, took over brewery operations. Guinness's only economically unsuccessful child was Edward, who fell into debt after investing in a failed
ironworks company. In 1811, a bankrupt Edward Guinness fled to the
Isle of Man as protection from his debtors.
Politics and religion Guinness was politically active throughout his life, both as a supporter of his cousin-in-law
Henry Gratton and as a member of the Dublin Corporation. He was additionally a lifelong member and secretary of the Kildare Knot, a
dining club made up of wealthy individuals regardless of religion. During his tenure, the Knot was involved with the
Irish Volunteers, a patriotic
militia group dedicated to defending Ireland from potential French invaders. Guinness's primary political positions, however, concerned the rights of Catholics to fully participate in Irish politics and society. In addition to personally hiring Catholics for his brewery, and by accounts treating them fairly, Guinness advocated to overturn laws that restricted the ability of Catholics to enter certain professions, and as a member of the
Royal Dublin Society, he argued for economic developments that would positively affect lower-class Catholics in agriculture and domestic industry. He was opposed, however, to the
Irish Rebellion of 1798, a rebellion of
Presbyterian radicals who wished to overthrow British rule in Ireland. Guinness disliked both the economic disruption that the rebellion brought, as well as the violence. His son John was wounded in the fighting, further incurring the Guinness family's disapproval. Guinness's opposition to the rebellion garnered the ire of Irish Catholics and nationalists, who subsequently referred to his beer as his "black Protestant porter". Guinness was a deeply religious man whose personal
motto was
Spes Mea in Deo, Latin for "My Hope is in God". Although he never converted to
Methodism during his life, instead remaining a member of the Church of Ireland, his diaries indicate that his faith was influenced by that of
John Wesley and the Methodist model of evangelical social work. He served as treasurer and later Governor of
Meath Hospital and frequently donated money to
St Patrick's Cathedral, Dublin. Another religious inspiration for Guinness was
Robert Raikes, who promoted
Sunday school as a method of eliminating crime by introducing faith and morals early in life. In 1786, Guinness opened the first Sunday school in Dublin. Many of Guinness's social positions were based on his beliefs of temperance and moderation. He believed that the duty of the wealthy and powerful was to set a strong moral example for their citizenry and looked unfavourably at what he viewed as displays of excess. He once protested the traditional feast of a new
alderman, worried that the occasion would lead to drunken impropriety, and instead suggested that the money set aside for the banquet be donated to
The King's Hospital. Guinness's investment in penal reform similarly stemmed from his displeasure towards what he believed was excess punishment towards criminals. He was particularly opposed to the culture of
duelling among the Irish elite, which he viewed as a deadly sport masquerading as honour, but his efforts to eliminate or reduce duelling were unsuccessful. Despite his generally temperate positions, Guinness never ventured into the
teetotalism movement, instead joining the belief of his fellow brewers that drunkenness was attributed to liquor, not to beer. == Later life and death ==
