Jim, this is your friend from Canada. With all due respect, allow me to jump in here. This is what we're looking for:
JESSIE JACKSON, (daughter of merchant ABRAM JACKSON of Girvan) married JOHN MCNEILLY (son of WILLIAM MCNEILLY, brother of ALEXANDER MCNEILLY of Glasgow and/or Ayr) in 1879 in Grenada, West-Indies.
We are looking for info on Abram Jackson & family and William McNeilly & family.
The brothers John & Alexander “Sandy” McNeilly went to Grenada around 1875 as representatives of Thomson Hankey and Company of London.
About Jessie Jackson, we know the following:
Before moving to Grenada in 1879, Jessie was from Old Dailly, Ayrshire (near Girvan) and was born in Girvan Way, Croshill. She was an evangelist with a preacher named Powell in Glasgow. She may have worked in a baker's shop at Charing Cross. She had a brother Abraham, a brother Jim, and a sister.
One of John McNeilly's granddaughters RUTH LEEDHAM, moved back to Scotland and married a mister MCMILLAN. This McMillan family, related to all of the above, is reportedly still living in the Glasgow area.
