Hello Boop, I could go into the library for you - or you can phone them on 01383 312600 and ask for the Local History section to ask what records are available. They are very helpful re. resources but I could look up anything which would take time.
If your Ferguson's were so hard up you think they might have received Poor Relief, it seems unlikely they would have afforded a notice in the paper, but I know the library has back copies of the Dunfermline Press (local paper) on microfilm. Do you only have the years of death or can you be more precise? As I said on another thread, I believe that information on burial lairs for the area from 1867 is available from the Cemeteries dept. tel: 01383 724653. So even if they could not have afforded a headstone, there might be a record of them there. Or if you're not in the UK I could do the phoning for you.
Let me know what you'd like me to do.
Trish
