My McNamara's start with Margaret, born Lochananbrone in c1838. She married a Michael Joseph Butler at st Cronans in 1872. Their first son, Patrick, was born there the following year and they moved to England soon after.
Margaret's parents were John McNamara (a farmer, b Drumaneen c1810 d Lochananbrone 1878) and Mary (? b c1816 d1907). They had at least 4 other children -
James (c1830),
Ann (c1832)
Thady/Timothy (c1835) and
John (c1842) - who married a Catherine O'keefe in Crusheen parish church in 1867. They had 8 children - Timothy , James Mary Michael, John, Bridget, Catherine and Thomas, all born between 1867 and 1890 in or around the Lochananbrone area.
The family tale is our McNamara's lived at Stonepark house, which subsequently passed to the O'keefes.
John senior's mother is thought to have been Bridget, (1787-1864) but I know nothing about his father. He had at least one brother, James, who possibly married a Mary Maley.
Apparently, Loughanabrone no longer exists except as a local name. The area is now called Caheraphuca (also spelled Caherafooka, Caherapooka in 19th c.) Translated from the Gaelic, Lougahanabrone it literally means “The little lake of sorrow” possibly indicating there was a drowning there at some stage. But the lake itself no longer exists.
Hope some of that helps someone.
