I have been searching for my great aunt, Emma, known as Clara, Rock who married a street car conductor named Collins circa 1900. I have found one street car conductor named Collins in the 1900 index but he was still single and lived in a boarding facility. His given name was Joseph and I am fairly certain this was her husband. They had a daughter named Vesta. She was pictured on a postcard sent in 1909 and appears to be about five to seven years old. I am sure you are all aware of how many districts were in Milwaukee in 1910 and if you have looked at the census (on Ancestry.com) how many pages are almost to totally impossible to read. Is there some record of street car conductors for the first several decades of 1900 where I might find an address or other information about Joseph Collins and his family? I would really appreciate any suggestions. I have searched areas around anyone with the surname Rock in case they settled near there but have not found them in those locations. Patti
