I think you are wrong. You said "In the 1870 census of Gordon Co., Georgia there is a Malinda Pinion age 60 born in S.C. She has a son James Fletcher Pinion age 21 born in Georgia." PINION would have been her married name in the census not her maiden name. PINION would be their fathers name and her married name. This woman was born a PINION and married Joseph CHITWOOD. She is not the woman in the census and not the woman Sharon is looking for.
