Hello from Australia - according to my gg grandmother's records, we presume it to be the Prime minister BUT perhaps it IS another Ramsay Macdonald.
My gg grandmother was Catherine Collins (nee Paterson) born 9/1/1849 daughter of William and Margt Paterson of Stirling. Catherine's siblings were Jean, Mary, Alexander, William, Robert and John PATERSON.
I also have in my possession some letters written from Scotland by a Sarah and Elizabeth PATERSON. If you see any connection please email me.
With many thanks from Carolyn in Queensland, Australia
