Rozenberg Piotrkow Trybulinski #general

Carin Miller

I found 2 Haskiel Rozenbergs on JRI. One of them is my great great grandfather.
Haskiel Roznberg from Ujazd, born 1829, index # 740777, line 29
Haskiel Rozenberg from Piotrkow, born 1839, index # 715805, line 29.
According to my searches, the family lived in both places at different times.
How can I use the index info to access further formation? How do you order info from LDS.
