My husband's mother was an Afrikaans woman named
Bertha Maria; I guess they were family names (her mother, whom I knew, was
Gertruida Susannah Maria but was always known as
Dollie). She died when he was 5, and by the time we had our first daughter we wanted to use the names of both our mothers as mns, but
Bertha was too much for us so we used
Mary instead.
Her mother always used the Afrikaans pronunciation - BEARtah - but by the time she met my FIL she had switched to the English version.
