Hi
Unfortunately I do not have any information that includes those names. The farthest I go back is to William, George and John Allen's parents - Robert and Sarah. William was born in 1800 in the parish of Ballysodare, Sligo County, Ireland and married Margery
Morrison Apr 19, 1822 [my line]. George, born in 1808 married Catherine
Morrison and John, born in 1809, married Mary Alexander. Their father, Robert, was a clerk for a lawyer named Argu in 1776.
Any of that sound familiar?
