If Frances Mary Cockersole Cope was born in 1822, why can't she give birth to Jane in March 1842 and Mary in September1843
I have a copy of Jane's baptism doc. certified from BDMNSW , Father Joesph Cope, Mother Mary, Parish of Rowan.
Also, on my great grandmother's birth certificate, (Jane's daughter Florence) Frances Rose is listed as the witness.
You even mention Jane, as one of two known children, in Joseph Cope and Frances Cockersole profile biography on Wikitree, but haven't added her as a daughter .
