I just came across this topic by chance today and so glad I did. I am in New Zealand. My wife is related to Henry Layton Stephenson (who is John's brother), through Henry's 2nd Marriage to Annie Sheehan. 1st Marriage was to Isabella Parks. (Amended actually is Park)
Henry was born 11-1-1832 in Singhee Bengal India. His father John was at that time Superintendant of the HEIC Saltpetre Factory in Tirhoot Behar, having left the UK in 1829 being the year John Atlantic Brumwell Stephenson was born during the voyage. Henry and John were baptised 1-4-1833 and as previously mentioned in previous posts John was recorded as John Bromswell Stephenson.
Whilst in Bengal John Snr wrote a number of Articles for the Journal of the Asiatic Society Bengal, (See Vol's 1 to 5 1832-1836 available online throgh Google Books Search) a Treatise on the Manufacture of Saltpetre and a number of Journals. I also believe he was responsible during one of his journeys in Tirhoot for finding a relic which was to prove of great significance to Buddhism. This was donated by him to the Asiatic Society.
Having read these Articles it is clear that John Snr was a very well educated and intelligent man. He is also stated to have been a well known Chemist involved in the Tyne Chemical Industry for a good number of years before going to India.
From what I can ascertain the Family returned around about 1838, this being when all the other children born in India and Leonard who was born in England in 1838 were baptised at Bishopwearmouth. In 1841 they were living at the Peak Alum Works where John Snr was the 'Agent' (my wife and I visited there July last year on our first big OE and it is a very lovely location),although the 1841 Scalby Census has all the family being born in Yorkshire we know this is incorrect (at least for Elizabeth and the Children exclulding Albert).
Alfred Septimus Stephenson was born in Heworth in 1843 a year before John Snr died. John died December 1844 at Heworth Shore (occupation stated as Chemist) interestingly burial records St Mary's Heworth were under spelling of Stevenson.
Elizabeth died 1878 at 19 Ravensworth terrace Gateshead (part of this building is now located at the Beamish Historical Centre and again we visited this last year also).She is stated as having been buried at St Mary's Gateshead but I wonder if she would have been buried with John.
For some time I couldn't understand the situation with Elizabeth Gordon Brumwell and her siblings (born 1804-1809) being all illegitimate with mother being Elizabeth Gordon and Father William Brumwell (a Surgeon) given the Social Stigma and William's standing in the Community. However a Brumwell relative provided the clue to the Serial Illegitimacy as William was previously married to Susannah Wilkinson but they seperated following her Adultery (as documented in previous post re the Trial of 1793, at it was only in 1810 (presumably on Susannah'S Death) that Willam and Elizabeth were able to marry. Catherine being born 1811 and after marriage hence being recorded as 1st child of the marriage.
Maggie360 I would love to get a copy of John Snr's Journal of the voyage to India when you have transcribed, if possible.
I have more information on most of the family which I have gathered and happy to provide.
For those with interest in the Brumwell connection I would recommend getting a copy of the newly reprinted book ' The Peninsular war 1808-1812 Letters of a Weardale soldier, Lieutenant John Brumwell, by William Morley. Eggleston 1912. Page 95 refers to William Brumwell's daughter (Elizabeth) marrying Mr Stephenson a chemical trader on the Tyne and their son born during a voyage to India in 1829 ......' Book also has a genealogy of the Brumwell's. It is available Amazon.comand cost me US$10.99 plus postage.
Also available Amazon Uk 'The Trail at Large of Sir Matthew White Ridley,Bart....for criminal conversation with the wife of Mr William Brumwell,... before Lord Kenyon, at Guildhall, March 4th 1793...' Cost was GBP18.19 plus postage.
