My grandfather, Karel, was from a large Czech family living in and around Loket. He had many brothers and sisters, who seem to have spread across Europe with at least one large family from his brother in Germany and a sister in Holland. My grandfather came to England in the early 20th century and was a glass blower.
If you are possibly a part of my family (my great grandfather's name was Anton) I would be pleased to hear from you.
I know that two of my mother's Czech cousins were still alive in the 1980s and had families of their own and we visited a German cousin in the 1970s
