bukldy on Family Tree Circles

I am searching for descendents of Thomas Dvorak, Joseph Dvorak (his brother), John Dvorak (half-brother). All lived in the Chicago area. My grandfather, Thomas married Anna and they lived on Keeler Avenue during the Census. Their children: Thomas II married Ella Lusk, Joseph, married Clara Frankenfield, Bessie (died in the Eastland Disaster of July 25, 1915), Caroline (my mother), married Edward Anton Kepka, William never married. After Uncle Thomas died in 1944, his sons, Thomas III and Edward were to have gone west to get jobs in the western movies. Mother lost contact with them and with Tom's wife, Ella.

Dvorak is such a common name that it is impossible to find, for certain, information regarding the brother and half-brother. I have listed some surnames that are in my tree and if anyone out there recognizes a possible link to their tree, please contact me by email.

Thank you.
