I really still am lost with this name, all I know is that my great grandfather was Bottalagine and he lived in italy. He only, as far as I can tell had daughters. But I'm not sure on this, one of his daughters lived in England and died about 3 years ago (not sure if it was longer). I also know that he was in the Boer War and may have had a sibling there with an african woman, but this was only a story my grandfather told me so I'm not sure about that yet.
If you find any news on that line, please let me know we may somehow be related as the name seems to not exist.
