[Ger-Poland-Volhynia] Tekla and Charlotte

[Rose Ingram]

Recently I have been looking at film 729253 (civil) Catholic records in 
Gostynin parish.  On two different birth records for different families the 
mother's name is shown as Tekla.  Other birth records have the name 
Charlotte.

Does anyone know if they are the same name  Polish - German.  The reference 
book I have does not help.
