Guillaume Grou was elected Consul of the Merchants in 1745, alderman in 1748 and Judge-Consul in 1755. His father, Jean-Baptiste, had been Judge Consul and alderman of Nantes. Guillaume was associated with the activities of his father, which he pursued after the death of this one, with his brother Jean-Baptiste. Between 1748 and 1751, the company Grou & Michel, endowed with additional capital, participated in the slavery trade sadly famous under the name of "triangular", and accounted for 21 % of the slave shipments from Nantes. In total, from 1714 to 1765, the Grou family financed 114 expeditions, more than half of them for the slave trade. Their fortune then exceeded a million pounds, allowing Guillaume to buy, for 60,000 pounds, an ennobling charge. The Grou allied themselves with powerful families: Clinchamp, Mare d'Azincourt, Prud'homme-Fontenay, & c. We find their weapons here and there, clearly identifiable, in connection with these different alliances. In the eighteenth, we find their traces and their activities in the Caribbean, especially in Santo Domingo (today Haiti). On January 17, 1741, Guillaume Grou married Anne O'Shiell, daughter of Luc O'Shiell, one of the three wealthiest shipowners of Nantes. By this marriage, Guillaume Grou entered the milieu of the Irish of Nantes, descendants of Jacobite emigrants active in the great trade. Ten years after the death of his father, Anne's family was recognized of noble origin by a decision of the Council and by letters patent of 1755. Guillaume Grou and Anne bought the domain of the Placelière whose Anne, his sisters Agnès and Mary , as well as their brother Luc Nicolas, had inherited from their father. The couple had the manor completely rebuilt in 1747-1748. During the second half of the eighteenth century, the Manoir de la Placelière was the place of reception par excellence for all the families of Nantes, including those of Irish origin established (O'Shiell, Stapleton, Walsh, Clarke, O'Riordan, Murphy, Browne, White, Hay of Slade). He built, between 1747 and 1752, the hotel Grou, 2 place of Little-Holland, on the island Feydeau in Nantes. Guillaume Grou died in 1774, and made important legacies "in favor of humanity" including 200,000 books for the creation of an orphanage in Nantes, where a street of the city and a building, the Hôtel-Dieu from Nantes bear his name. Anne O'Shiell remained a widow 17 years, dying June 30, 1793 while were recorded the deaths of many fighters of the battle of Nantes. Without descendants, their property was confiscated during the famous day of the dupes, in circumstances remained controversial. Its weight is 92 kg.
