After some looking on Ancestry.com, it appears that your Thomas Frank Tabasinske is the son of Thomas Tabaka (1793-1875). The evidence is circumstantial, but I believe that it is strong enough. Thomas is listed on the 1885 Iowa State Census records for Cass County, Iowa. Also, listed on the 1885 Iowa State Census records for Cass County, Iowa are Michael Tabasinsky (aka Michael Tabaka/Tobaka/Tobacco) and Mary J (Tabaka) Glowczewsky. As I mentioned in my previous post, he is definitely the son of Thomas & Frances(ka) Tabaka based on his Civil War service records. He is the only person with even a remotely similar name to serve in the 7th Independent Battery of the Wisconsin Light Artillery. Both the Tabaka and Tabasinsky names are listed on his pension records.
Since the Iowa State Census records list the birth date, the birth place, the parents names (including mother's maiden name) it is easy to verify that this Mary is the daughter of Thomas & Frances(ka) Tabaka. She listed her father as Thomas Tabaka. Her birth place is listed as Wisconsin, and her birth year (1852) is identical to the birth year listed for her on the 1860 Federal Census in Barton, Washington, Wisconsin.
There is a grave for a Thomas Tabasinsky in Victoria Cemetery, Massena, Cass County, Iowa. I assume that this is your (and my) Thomas Tabaka. This spelling provides a further linkage between the Thomas Tabasinske and Michael Tabasinski on the Iowa Census.
Her is the link to Thomas' grave site:
