There is also the following which if we didn't have the shipping record on PROV [and possible death in NSW] could be believed ie born 1827 which tallies with age on 1861 census.
Deaths Sep 1885
Waghorn Sarah 58 St. Saviour 1d 32
I am far from convinced that the info on the family tree is accurate - Has the tree been assembled from data as we have found without supporting evidence eg certificates. I have also found a L Johnson on the ship mentioned but aged 7 on PROV. I only mentioned the shipping record cited - I also think it is Sarah with chn and mother [age is incorrect - should be 65] What happened to Edward A?
The shipping records on Ancestry also include crew. My grandfather was a marine engineer and in the 10 years prior to his marriage in 1910, he was involved with coastal shipping. I have found all his 'trips' into Sydney from 1900 to 1909...age differs a couple of years at times, but the years worked and especially the names of the ships, are remembered by my 97 year old father....who has an excellent memory. Soon as I started mentioning the ships' names, he added more.
Wonder if it would be worthwhile someone having a look at the shipping record at PROV.... Was the original manifest on findmypast clear?
Final comment

It is all too easy to make data
fit one's tree!! Certs are needed.
