I am looking for information on and descendants of an Allen or Allan (spelled it both ways) family of Galway. Hugh and
Andrew Allen of this family went to Glasgow, Scotland in
19th century and founded Allan Steamship line, which ran a single (as I gather from steamship histories) liner across the ocean, often full of emigrants. They may also have had business or family connections in Arran. My 3X great grandmother, Catherine Allen, married at about age 16 Nathaniel Lowe, and had her first child possibly in 1837.

The family were supposedly respected landowners on the coast of Galway, maybe even among the first families (I suspect my great grandfather could speak blarney), and they were Protestant. They were originally French Huguenots, with the name Alleyne, and were driven from England to Ireland during one of the Tudor persecutions of Protestants. Catherine had a remarkable and strong willed temperament. The family clearly took pride in their heritage, as Catherine told the family history to my great grandfather. Most of the family stories are supposed to have been about her. Apparently, she had a broad, squarish face, as my grandfather and his daughters supposedly took after her.
