There was a Thomas J. Haskins who divorced his wife, Susan in Collier, Florida on 12 Jan. 1996. This is certificate 000553 Florida Divorce Index 1927-2001.
I am wondering about Thomas Haskins brother, Allan or Allen, and whether he and the two sisters could still be living. If any of them are living, a search could take a different tac than records that are available for a deceased person. If you could locate one or more of them, they could be a good resource for answers to your questions about earlier ancestors.
