Don't know that I can be much help. But! I have a JANE CONSTANTINE in my family tree. She was b 1833 at Tyldsley, Lancashire. England. She was the daughter of GEORGE CONSTANTINE and SARAH ALLDRED.. Sarah's mother was a JANE ?, and she was married to a PETER ALLDRED.
They may have had the following sons: PETER, ; WILLIAM  and JOHN as well as SARAH [June 6, 1803, at Tyldsley]]
As I said may not be of any help, but if it opens up a new thought for you, Great!
