Hi Meabbie,
I have a Hessie Kennedy in my tree too  (  

 )  - but too contempory for you (  

 )
Can't really help you here, but I am interested in the name Hessie,
especially as "my" Hessies have connections to Antrim.
We have a tradition in my wife's family that the oldest daughter is always called Hessie.  
Full story here: 
http://www.margulies-chronicles.com/i-legends.php#hessieDo you have anything similar, or have you heard of any stories or rumours of this in any other branches of the family ??
Good luck,
Bob
