what information does antonia pass on to jim during the thaw visit?

Ántonia explains to Jim that her father is sick and depressed at having left the old country. He misses playing the fiddle with his friends, and he had not wanted to come over originally. Mrs. Shimerda wanted to come to America because she thought that Ambrosch would be able to become rich here. Ambrosch is considered the most important person in the Shimerda family, and even Ántonia is in awe of him.
