Hi List, When using the IGI search facility (within Custom Search) I have found that the seven digit batch numbers work better when you add the sheet number as well. I then have changed the sheet number to look for other family members. I discovered this when I had two known family siblings with the same 7 digit batch number but 20 sheets apart. Someone correct me if I am wrong, but I understand that the seven digit batch numbers are not the same type of entries as the C(6 digit) numbers. Regards, Jan Vernon Sydney, Australia
