1) In fact blank lines should be omitted. This is almost universally true for all AWAP projects. (Family Search does things differently)
We are not keying the name of the clerk who prepared the record (signature at bottom), nor the names from the header.
Signatures of the men payed is another matter, we will take the most complete version of the name, with the signature winning in case of differences in spelling.
2) we do not key "first" or "second" and just leave the day blank when it is encountered.
