Hi Tania
This may be the lady you are looking for. As you will see she was born as Phyllis Reardon and died as both Phyllis Reardon and Frances Jean McCoy as the rest registration numbers are identical. I have not had any luck finding the mother though "Geneva Ann Reardon".
I have enclosed some other information that maybe of some use to you.
Regards
Adelina
