Hello. Well as a former bill collector, it's pretty easy for me to skip trance and find people. Using a website that the company used often, zabasearch.com, I believe I have found her. I don't want to post someones info on this website, but if you go to zabasearch.com, type in her name and don't select a state and hit the search button. It will bring up a complete list of ppeole with your sisters name, but midway down, you'll see a Mary Sickle born in 1958 who resides in Lansing, MI. Hope this helps. Take care.
