The Local Government (Ireland) Act also caused a number of county boundaries to be modified, with the result that a number of baronies now cross county boundaries. This can cause confusion to genealogy researchers, who may be unable to find an area referred to as being in a particular county in 19th century sources in the modern county. Most markedly, the entire territory of the small barony of Kilculliheen was moved from County Waterford to County Kilkenny. Likewise in 1976, when suburbs of Drogheda were transferred from County Meath to County Louth, barony boundaries were not adjusted.
