Dr. says thyroid tests normal but tsh increased by more than point and t3 (liothyronine) low with all the symptoms, 2 sibs w hypo, now what?

Find a holistic MD: There are numerous factors that can indirectly affect thyroid function. Do you have symptoms? You can visit my website and 'test yourself' for low thyroid function http://www.Woodlandswellnessmd.Com/questionnaires.Htm if no red flags, then you can monitor levels again in a couple of months.

Check reverse T3 (liothyronine) : Looks like peripheral t4-t3 covers ion might be inadequate. Either use armor thyroid or use compounded t4/t3 combo (need 2% as t3).
