Audrey J Stetson

I read that, I have a relative by marriage, who is also researching the family name of Stetson. Her name is, Audrey J. Stetson. She resides in, San Marcos, California. However, I have been unable to reach her by phone. Whereas, I found her phone number, as well as address. Although, she is not answering her phone. My hope is that, we can exchange Stetson family history information. Please help me, in contacting her.
