Angus,
One of the purposes of the pre-1700 protocol is to avoid creating duplicates, since people that far back in the tree likely have LOTS of descendants.
Please take a look at these profiles that are already existing here. If you need help with the merging process--just give a shout out here at G2G and many folks will be happy to give you a hand.
These are the same people:
[[Ferreira-113|Manuel Ferreira (abt.1657-)]]
And
[[Ferreira-5673|Manuel Ferreira (abt.1655-abt.1700)]]
Their descendants from
[[Ferreira-5672|Ignatius Leopold Ferreira (1695-abt.1772)]]
and
[[Ferreira-112|Ignacio Leopold Ferreira (bef.1695-1772)]]
need to be reviewed and merged as necessary.
