Hello Shirley,
do you have a tree on Ancestry or elsewhere on the web?
I find the LAN-OPC is a good site for parish records and I recently wrote a script for myself to export data to an Excel spreadsheet.
Basically what I do is search the
Lancashire OnLine Parish Clerk Project - Search website and then mark the data which is returned (I choose to display all records). I then open notepad, paste the data and save as a text file. I then run a script which parses all the data (read it all) and then splits all the lines into fields and saves them to Excel.
It needs a bit of tidying to sort the columns into a more preferable order and add headings to a few of the less important columns, but I could run this for you to identify all the SOUTH and SOUTHWORTH families within a maximum of 90 miles of a specified church (you can't search for anything over 90 miles away) and send you the Excel spreadsheet.
Is there anyone specific you are having particular trouble identifying?
Feel free to send me a personal message.
Regards
