Query on Ambrose Alchin parents

Ambrose Alchin, Snr, Free Settler "Palmyra" 1838 born 1800 died 1877 is on Geni with 2 sets of parents

Set 1
* Thomas Loudwell Alchin born 1771 died 1831
* Sarah Alchin born 1770 died 1847

Set 2
* Charles Alchin, Free Settler "Palmyra" 1838 born 1837 died 1908
* Mary Alchin born 1843 died 1897

Charles and Mary cannot be his parents as they were born 37 years after him

Ambrose had a son born 15/4/1837 Charles Alchin, Free Settler "Palmyra" 1838.who according to http://dunn-brigden-familytree.com/b4.html#P523 married Mary Stear

I will move Charles from his parents to his son.
