Ancestry.comis to open its international headquarters in Dublin, creating 35 jobs over the next two years.
The family history resource will move into an office on Sir John Rogerson’s Quay in September, with the official opening of the premises taking place later in the year.
The company took temporary offices in the city last year, and currently employs 15 people.
Ancestry.com's vice president and general manager of its international division, Olivier van Calster, said the firm felt Ireland was the perfect location for its offices.
“Ireland was chosen for a number of reasons, not least because of the great availability of talented people, but also because it is a country that has a long history of emigration and plays a significant role in the family history of people across the globe,” he said.
Minister for Jobs, Enterprise and Innovation Richard Bruton said the company was “a very welcome addition to Ireland’s growing cluster of online companies”.
The site, which was launched in 1996, recently reached the two million subscriber mark.
The family history archive has in excess of 10 billion historic records and images, some of them dating back to AD 1270, covering more than 40 countries.
