Hi there,
Among the children of John Ewbank and Susan SIMPSON you will most likely have a son, also named John Ewbank.
I wonder if there is a connection to Susan’s family and perhaps School teaching continued through the children of John Ewbank and Susan SIMPSON (nee Baker).
In the SMH 17 Jan 1880,
http://trove.nla.gov.au/ndp/del/article/13453917 Public Schools... The undermentioned gentlemen have been appointed to form the Public Schools Boards of the Public schools established at the places specified ..... Moonan Brook .... Messrs .... John Ewbank SIMPSON and Walter Samuel BAKER.
In the SMH 16 Mar 1910
http://trove.nla.gov.au/ndp/del/article/15146176 SCONE, Tuesday. Mr. Walter Samuel Baker, of Moonanbrook, a prominent resident of the Upper Hunter for more than half a century, died suddenly on Sunday, aged 64
From NSW BDM online index
Marriage 1873 (ie civil registration) Walter Samuel BAKER and Sarah SIMPSON registered in the Scone District. #3832. That m.c. should lead you to information about the parents of the bride and groom, but it is possible that there’s some blanks in the NSW BDM records for that marriage. Those blanks are not actually causing any brickwalls. The clergyman conducting the marriage was required to record the names, the prospective couple’s ages, places of birth, occupations and their respective parents names (including all former names of their mothers), occupations etc. It is just that NSW BDM received only a summary of the parish record and may not have reconciled the rural records with that summary.
From a SUBMITTED online tree, the date for that 1873 marriage at Scone is 11 Jan 1873, giving Sarah Simpson as born Whittingham NSW circa 1852 and Walter Samuel Baker as born circa 1846.
Hopefully I am not sidetracking too far from your original request, may I suggest you have a read of the thread
http://www.rootschat.com/forum/index.php/topic,546609.0.htmland also the image at reply #12 of the thread giving example of the dreaded blanks
http://www.rootschat.com/forum/index.php/topic,557757.10.html I speculate that Sarah BAKER, nee SIMPSON could be a granddaughter to John Ewbank and Susan SIMPSON and further speculate that perhaps Walter Samuel BAKER may have been related to Susan Simpson nee Baker.
Fingers crossed that somewhere along the line you will be able to find some clues re the birth place for the John Ewbank SIMPSON ex the William Shand of 1825. I am not convinced that this thread has provided proof that he was the one baptised at St Michael Cornhill, London.
Cheers, JM
