Hello
this needs deeper investigation however I think there may be a connection. Jane & Charles could be siblings.
I believe Jane HOWARD was born 1832 in Barley Hertfordshire (1841 census). Her father George was born 1786 and Sarah 1816. Both born Hertfordshire.
I checked the family search website and found the following issue for a George & Sarah HOWARD:
Benjamin christened 16/4/1826
William christened 18/7/1828
Jason christened 25/4/1830
Jane christened 10/6/1832 ..your Jane?
Charles christened 27/4/1834. (This could be my Charles)
There is a marriage for Jane HOWARD and Abraham BRIGHT on 25 March 1853 Barley Hertford.
Victorian Immigration records:
Abraham & Jane BRIGHT arrived 1855 in Victoria, Australia aboard Ravenscraig. No children listed as being on board.
Had no luck locating Charles HOWARD on immigration records.
cheers
Kim
