They were transcribed under the name PERCY. I sent in a correction.

Harriet died 8 July 1901, burned to death.
A Mabel Mitchell, aged 8 also burned to death 8 July 1901.
Sarah Jane Perry was informant for both.

Found this marriage before but didn't know if it was Philp and Sarah or not but am pretty sure that it is.
