There is a Henry Krone b.Bremen c.1843 with a daughter Anna aged 2 on the 1881 Census of England. I believe him to be the brother of my g-grandfather Gerhart Krone. They apparently arived in England togeher, although there is no trace of Gerhart on the census, but Henry migrated to USA shortly afterwards having spent only a few years in Liverpool, England. Gerhart stayed and later changed his name to Gerald Crown shortly after marrying my g-grandmother in 1885. Hope this is of help.
