My grandfather Peter lived in Parvomai- small town situated near Plovdiv. He met my grandmother in Simeonovgrad where she lived with her family

My grandmother and my grandfather moved to Dimitrovgrad when my dad was still a child. My dad grew up in Dimitrovgrad - Bulgaria. 
I remember my dad mentioned that his grandfather (his dad father)had a factory in Parvomai for shoes and even made the boots for the Bulgarian king Boris, but how accurate is the information I am not sure. 

There was one Kolarov, who was even Prime minister of Bulgaria after II. world war, his father was Peter and was a shoemaker.
