Looking at Fred Nerks post about #271 and post #279 and this post with the actual image is it possible that ‘Soebarkah’ is not a persons name at all.
But could it just be the village/city name?
We are so use to the nomenclature of city, state here in the US. But was Indonesia divided into provinces or states? Even if it was would there there be enough villages or cities with the same name to worry about using the province or state in identifying a village/city?
And if the President of the Country was from or had connections to that village (as FN says in post #271) it must be well known.
So is this name not a persons name at all - is it just a place?
