I have had a look for baptisms for MARY CHRISTIAN & there are quite a few but most are later than yours, I did find the following one that seems to fit the dates you are after:
Baptism : 3 JUN 1696, MARY CHRISTIAN, D/O, JOHN/MARTHA, (NOTES: OF BARROW), COTTESMORE
The other earlier baptisms (which I think are most likely too early) are:
12 SEP 1669, MARY CHRISTIAN, D/O, THOMAS/ANN, (NOTES: OF BARROW), COTTESMORE
20 MAR 1663/4, MARY CHRISTIAN, D/O, THOMAS/KATHERINE, COTTESMORE
As I said there are quite a few more but they are from 1701 onwards.
Back with marriages soon....
