Allan Fea in "The Real Captain Cleveland", which was published in 1912 writes:
| "Old John" is still remembered as a locksman, and a daughter is said
to be still living in Cleveland, Ohio. Her brother Alexander, who migrated
to America in 1849, died there two years ago at the same age as his
father. The sons of another brother who went to America, it is said, are
now cow-boys. The Real Captain Cleveland, Allan Fea - p202 |
The daughter living in Ohio is thought to be Helen Fea, a daughter by John's second marriage, who married Alexander Winton. She followed her family to the US as a widow. Her brother, Alexander Fea, went much earlier as did Thomas Brown Fea, a son by John's first marriage.
Catherine died on 4th January 1869 at Blackhill Locks, Springburn Glasgow. The informant was her son in law, Alexander Winton.
