1099-B Cost Basis for stock received as gift and sold years later

This is a convoluted situation.  Have never sold stock.  The 1099-B does not have a cost basis for some of the shares involved.

On August 25, 1997, my wife received 6 shares of General Electric Company stock from her father.  He is now long deceased.  No record of his cost of that stock.
On May 18, 1998, she gave 1 share of the stock to me and one each to our two minor children  as custodian.
She retained 3 shares in her name.  Her stock certificate was dated May 18, 1998.
On November 7, 2019, the 1 share of stock of one child no longer a minor was transferred to my wife  due to the child's death on October 12, 2014.
Linda sold her shares on August 9, 2019.
Joseph sold his shares on August 9, 2019.
Linda sold the shares inherited from the deceased child on November 19,2019.
