This surname is not german at all. It is beared by travellers to NY that have an Irish name like Bridget Kearse or Patrick Kearse. But in the Dictionary o Surnames I use there is no explanation about the surname Kearse. I have only found Kearn. an Irish surname, meaning "descendant of victorious". The Kearse immigrated in USA at the beginning of last century are very few:only 10. Anyhow the origin of Kearse in Britain is not clear.
