Hi Everybody 11th July 2020
I would like to mention--that as I am Hungarian born, in my view: --Lajous with a strong probability could be the Hungarian Lajos.
I wonder, do you have another name, in addition to the Lajos/--as Lajos is a 'first name' Equal? a variation of LASZLO?--Laci ?
Or in my understanding in a 'Slovak' language--might be Lagyislav--, with 'Cirril' lettering ( I do not have on my computer)
As for Ludovicus? I wonder it may mean 'son of Ludov'--.
Best wishes to all
