ADAM family of Pitnamoon, Fordoun Parish

[pgaylia]

My 4*Gt Grandparents were James ADAM (born 1761 Arbuthnott- ?) and Margaret GRAHAM(E) (1769 Fordoun to 1823).  They lived at Pitnamoon farm from 1806 or earlier, until at least 1823.  According to a magazine clipping about Margaret's death in 1823, they had 20 children, of whom 17 survived up to that point.  I have found birth records for 17 of the 20, and two of the three child deaths.  Can anyone tell me who the other three children were?  In particular, I'm looking for a Mary ADAM.
