We are definitely from the same family.
I am in Melbourne and my father is decended from Philip Ilott.
Philip and Sarah Ann's son Herbert John Ilott was my father's grandfather.
I have 4 Word documents on the Ilott family from Philip b. 1800 and married to Mary Roe/Rowe.
It appears that Philip John b.1833 married Sarah Ann Keeling in Qld before his first wife Ellen Donald died in Liverpool.
I do not have any info on Philip leaving Liverpool so would be very interested to read about this, please.
If you would like to send your private email I will be able to attach my Word documents (this can't be done through Ancestry messages). My email is email@example.com
