Elizabeth Rockwell & Jehu Wilson

I need somebody's help! I am looking for a Jehu Wilson who was married to a Elizabeth Rockwell. The way that I understand the situation is that Jehu was a abusive husband.
I also am led to believe that someone out there has a diary that Elizabeth wrote. It is rumored to contain her description if how awful her life was with Jehu.If anyone has any information,or even knows the where abouts of this diary PLEASE let me know!
I need this info. to help complete my family history. I have worked to hard to stop now.
So, please, once again does anybody know anything about this? If so email me direct at rwilson43068@yahoo.com
Thank-you
