Looking for sisters Mary and Frances Handcock both born Coldridge. Name is often shown as Hancock.
Parents were John Handcock and Grace Eldridge.
We know the parents sailed to Australia with two sons. Parents John and Grace Hancock had left Coldridge in England and arrived at Fremantle in 1830 with their sons, George and James. Two daughters had remained at home in England and the family were never to meet again. A third son had passed in 1812 at age 8.
They arrived on the Warrior 12 Mar 1830 based on this passenger list
http://members.iinet.net.au/~perthdps/shipping/warrior.htm The Gregory family was connected to the Handcocks by marriage. Sophia was married to John and Grace's son George. More info in links on the page regarding the ship.
We have a baptism for Frances 10 Feb 1803 and for Mary 17 Nov 1807 both in Coldridge. No sign of them after that but given the info about parents and siblings leaving them behind, we assume they were alive when family sailed.
We have found a marriage for Frances Handcock to a Humphrey Drake or Dark 10 Aug 1824 in Coldridge but don't find anything to confirm parents of Frances and we have seen several Frances Handcocks listed in marriage records from Devon. A number of trees support the Humphrey Drake/Dark marriage but supporting documents are missing.
Some sources say Frances passed in Western Australia but again no support and it seems she would have reached out to family already there.
We cannot find Mary after baptism but assume she was alive when parents sailed.
