text: Based on the question, I would say you don't have an exact date of birth on these sisters.  Anyway of getting the dob's?  It will be very hard to find them with such limited information.  You said you are looking for free help.  Since you have little to nothing to go on, it might be better to find someone experienced, for a fee, to help.  If you have more info and post it, I will see if I can help.
