Funeral Expense For My Father in law

My name is Brenda Tavares my father-in-law was Steven Tavares we found that he had stage four lung cancer the doctors give him six months we brought him home and two weeks later the cancer had taken his life. He Fought for our country in the army. He was a beloved Father and husband & he never met a stranger he helped anyone.
