I am looking for any references to William McIlhagga (or McIlhaggie) b.1819 in Ireland , recorded as a farmer in Greenock after about 1844, married to Agnes Cosh (or McCosh). Thomas McIlhagga b.1868 in Greenock, who married Margaret Galbraith in Liverpool c.1890 and after the birth of daughter Agnes Barbour returned to Scotland, possibly Glasgow. Morag and Sheila (or Shelagh) McIlhagga, probably sisters, who may have lived in the Glasgow area in the first quarter of the 20th Century. Margaret McLean, b.1868, probably in Tobermory, Isle of Mull, who was possibly a twin, and her father, Donald McLean, a mariner. Many thanks. <donald@mcilhagga.net>
