A US-based ancestry search service has promised up to 35 jobs in Ireland over two years after it opens a new office in Dublin this year.

Ancestry.com is set to run its international operations from Sir John Rogerson's Quay.

The company has been in temporary offices in the capital since autumn 2011, and will move into the new premises in September.

Employee numbers in the Dublin office currently total 15 but are expected to grow to more than 50 within two years.

That number will include staff working within management and finance functions, as well as website developers and member service agents.
