Curious About Family Tree

My mother was born Patricia Pearl Perryman. Passed away here in Jax. Fl. in 2001 I believe at one time she was married to Leroy O.Linster in Ill. He was born approx. 1931. I am trying to connect the dots to find out who if any relatives I have living and deceased. I found a Leroy Linster that died in Las Vegas in 2005

Thanks in advance for any help offered.
