Until recently I was unaware that Sanlúcar de Barrameda was among the Spanish localities that hosted large Irish expatriate colonies in the early 1700s. I spotted the following entries in the course of some recent work in its parish registers:
Marriages 1715-1724:
P. 9V, 10 Dec 1715: Pedro Eston, native of the city of 'Dublino' in Ireland, son of Juan Eston and María Thaf, to Doña Catalina Narcisa de Ávila, widow of Bartolomé Álvarez, resident of this city.
P. 231, 31 May 1722: Don Ricardo Nugent native of Dublin, son of Don Thomas Nugent and Doña Isabel Nugent; to Dª Francisca Ortiz Marujan, legitimate daughter of Don Luis Jose Ortiz & Dª Andrea Marujan Contreras, natives and residents of this place.
Marriages 1724-1732
P. 143, 9 Aug 1728 Patricio Walsh legitimate son of Thomas Walsh & Margarita Walsh, to Catalina Fare d. of Gerardo Fare + Catalina Guarde natives of Ireland and residents of this city. Witnesses P. Fr. Carlos French of the Orden de Predicadores and Don Pedro Pichardo.
P. 211, 19 Jul 1730 Don Patricio French native of the city of 'Galbia' in Ireland, legitimate son of Don Gerónimo French & Doña Susana Ormsby; to Doña Mariana Croquer Daughter of Don Juan Ignacio Croquer y Luisa Alvarez, native and both residents of this place.
P. 116, 28 Aug 1727 Diego Esmith, son of Thomas Esmith and of Cathalina Brum, to Margarita Lorenza, daughter of Guillermo Lorenzo and of Ana Guinsi, native of the city of Dublin and all residents of this place. Witnesses Don Carlos French and Don Juan Grove, both Irish, clergymen.
Possible names and surnames intended by some of the above entries include: Easton, Farrell or Farrill, Ward, Smith, Lawrence (Guillermo Lorenzo = William Lawrence), Quincy or Quincey (Ana Guinsi = Anne Quincey). Galbia is, I presume, Galway.
