My husband's Great grandfather James Meade was Treasuer at Montserrat and President on occasion between 1850 and 1890. Goerge H Irish is shown in his daughte's birthday book for July 14th, but no year, as is Ellen Irish and Martha Irish for different dates. Howard Fergus's book Montserrat History of a Caribbean Island shows an Irish as a coloured Puisne Judge in the 1850's
The Soc of Genealogists in London has on microfiche 'Caribbeana' a collection of lists of wills made and details of business transacted. The first Irish to be mentioned on Montserrat is 1654 William Irish is a member of the Council in 1688 and 9. Too many details to give here. You'd have top contact me seperately.
