Hi again,
The best I can see is this very confusing entry:
RG10/5332 42 20
Trevethin Southill
Tranch
Margaret Forest, head, mar, 35, b. Ireland
John, son, 10, scholar, b. do.
Patrick, son, 8, scholar, b. do.
William, son, 1, b. Mon Panterg (?)
Bridget Field, stepmother, wid, 54, b. Ireland William Field, son, unm, 28, Miner, b. do.
Sarah Field, dau, 4, b. Mon Tranch
The reference you quote has me confused as well.... HO107 is either 1841 or 1851

Not sure this helps much...
Tanja
