as requested - the Ohio emigration was very much family pull from the large group of initial emigrants in the mid 1820's (some leaders of which were Methodist lay preachers who organised large groups) - my own explanation of this considerable emigration from a few parishes Michael, Ballaugh + Jurby are dominant, is that tho driven by economics (high taxes/tithes coupled with poor farming/fishing) there was a very strong nationalist thread against the English domination in the church, trade and government - once you had a large coherent group in a small area that was ripe for development most emigrants prospered and called on younger relatives to join them - thus you had the comment that in Cleveland Ohio Manx married Manx unto the 5th generation of immigrant families - it was the great mobilization of the USA during WW2 that broke this.

Louisiana is not a usual place to find Manx
