Hello Darren,
On Scotlandspeople, you can waste money on searching, for example what you put in the search engine has to be exactly the same as whats on their certificate otherwise you will not get a hit.
With the name Curlet, most of them are in Ayr.
Their are seven marriages from 1855. till 2006.
So if you just put the surname Curlet, no first name and Ayr, then you will get 7 hits. for your one credit. they are most likely all related, this is only the index, but they will be there in your previous searches if in the future you wish to view them.
The same goes with births, there are 48 Curlet, births the whole of Scotland, 1855. till 2006, this would cost two credits.
42 of the above births are again in Ayrshire.
Regards,
Jonn.
