Thank you, both, for your kind replies.
My normal process, with UK records, is to raid the IGIs in a known parish, and surrounding parishes for every possibility, match up parents with children and marriages. I don't usually have too many errors. I do end up with a bunch of cousins, that I file away for a rainy day. They always manage to tie in somewhere.

Then I go to the pay sites.
Some of these people are driving me nuts. I know about naming protocols, and actually find it really helpful, normally, but this time I have people living next door to each other, with the same name, born less than 6 months apart, to fathers with the same name, marrying women with the same forename, having children with the same names - in one case the baptism was 3 days apart. Add to that the interchangeable names... Some were obvious, but Patrick/Peter and Isobel/Elizabeth had me stumped for a while.
Ah well. It was good to hear about the missing records. It was also good to have some hope that there are Patons in Scotland's People during that time frame. I was hoping it wasn't something like a mass land clearing, or religious purge that made them not register.
I am about ready to buy some credits at Scotland's People for the first time.
Thanks again!
