Vaclav Mazanek and Anna Myskova

I am looking for any information on my grandfather’s family. I was told my great grandmother was sent to Prague to give birth to an illegitimate child (my grandfather Vaclav) but records seem to show he was born in
Hluboka in district Chlum, Sedlcany. Vaclav was born on the 26th of September, 1851 and died in Kutna Hora on the 17th of November, 1927. His wife Anna Myskova was born on the 9th of November, 1866 in Lisice.
