Supplemental and Secession Registers

[Topspin]

Perhaps this question got lost in my other thread about Janet Armour. Is anyone familiar with a supplemental register of births for Kilmarnock and/or registers of the secession churches in Scotland? I wonder if Janet Armour and her siblings are listed there.

I would appreciate if someone could look up the the following documents for the birth of Janet Armour in April 1845 at the NAS. Or is there somewhere else I can view these documents? 

CH3/1337 Kilmarnock, Princes Street, (Clerk's Lane) United Secession Church, United Presbyterian, United Free

CH3/1021 Kilmarnock, St. Andrew's Free Church, United Free, North Church of Scotland
