For example, in 1854, John Brennan placed a 'Missing Person' advertisement in the Boston Pilot. He was searching for his brother Luke Brennan, Parish of Cloontuskert, Co. Roscommon. Luke Brennan arrived in the States in 1839. The contact address is Newport, Rhode Island. The contact name is James Maine. On the same date John Brennan was also searching for his brother Patrick Brennan with the same arrival date as Luke.
Another example is Julia Moriarty who placed an advert in 1866, seeking her father Denis Breanen who had worked for many years in Indiana. Denis was originally from the townland of Dreenaulive in the Parish of Kilcrohane and the Poor Law Union of Cahersiveen, Co. Kerry. It can be useful to say the name of the townland aloud and make a note of other possible phonetic spellings of the name as you will find a range of spellings for Irish placenames. Another research options is a search of the U.S. Federal Census for either the missing person or the seeker or the contact person named on each advert.
