We have a Hyman Haimovitch from Iasi in our tree although his son Morris that came to the UK about 1901 spelt it Haimovis on his wedding certificate and then as Haimovitz a couple years later on one of his daughter's (my grandmother) birth certificate and then later standardized to Haimovitch.
Only one son of Hyman came to the UK but we are convinced that other sons or daughters went to the US and lately we have started trying to look for connections.
You can see the complete UK tree downwards from Hyman through his son Morris at our family website
