this may not matter since you said you never sold stock before and all the advice provided so far makes sense
be aware that GE stock split 3:1 in May of 2000, so all the numbers post that date should really be tripled. So if you Father in law gave 6 shares in 1997, your wife should have had 18 shares if she never sold.
That one share from the deceased's child's estate should have been 3 shares transferred. If there was only 1 transferred , what happened to the other 2 shares?
