Yes, Lithuanian children often wore shirts with large collars.
My "Lithuanian" family lived in Bellshill and Bothwellhaugh from about 1902 to 1941. The family name was Sugzda (with marriages to the McKay, Wallace and McCaskill families). Eventually, they mostly moved off to New Jersey or Queensland.
My mother was born at 2 Store Place, Bothwellhaugh (just above the pool room); my g-grandparents both died at Park Place (near the footbridge) – my g-grandmum in 1930, and g-grandpa in 1941.
The family came to Lanarkshire shortly after the birth of my grandmother in 1901. They had lived in Lauckaimis, a tiny hamlet right on the border with modern Kaliningrad.
