Without a Will the rights to the inheritance are governed by Section 2105.06 of the Ohio Revised Code. (link below) The fact that the great granddaughter was living with your mother does not change any rights of inheritance. If your brother is properly administering the probate estate is a whole other issue and is too complex for a quick answer on this forum. If you're concerned about your rights, then I suggest sitting down with a probate attorney who practices in the county where the probate case has been opened.

Best of luck.
