It is interesting to compare the words with those in the Obituary for Edwin Henry Armstrong Newman. Many of the paragraphs are identical, hence I have doubts about the authenticity of that obituary too.
Transcription as follows:
The Newmans were descendants of John of Gaunt Earl of Lancaster on the female side. At the time of Charles I, Sir Richard Newman made the last stand for the King. Two baronetcies were granted to two Newmans of Cadbury, Somerset, a portcullis being added to the family arms by Charles II in recognition of services rendered by them in England and Ireland to King Charles I, one of such services being the rescue of King Charles II as an infant from Worcester Castle by Colonel Newman.
The entail of the Cadbury estate was cut off by his great uncle at the beginning of the 19th century. The baronetcy is one of the oldest in England. He was related to the Fanes, Lord Sandys and the Hoods, and most of the old families in the West of England, including Lord Nelson through the latter's mother's side. The Newmans, on their grandmother's side, were descended from Sir Joseph Jekyll, Lord Chief Justice of England, Great Master of the Rolls. The great grandfather was Captain Jekyll R.N., an old shipmate of King William IV, and was always at court with the old King. He was the inventor of the first lifeboat and ship's pumps, which were taken up by the Navy, also gun carriages that have only been superseded within the last 35 years. Captain Jekyll had to sell his estate at Roundhill, Somerset, to cover the expenses of his inventions and went to live in Paris where he died."
Correction written by my father H.E.M. Newman:- "Col Richard Newman (1620-95) lent large sums to Charles I and II, and was repaid by the grant of the augmentation, the portcullis, to his arms. He very likely assisted Charles II to escape to the Continent after the Battle of Worcester in 1651, when Charles (aged 21) was defeated by Cromwell. The first baronet was Col. Richard Newman's grandson, Sir Richard Newman, born in 1675, amongst other things MP for Milborne Port. His son (Sir Samwell) succeeded but died without issue. N.B: Baronets were first created by King James I (1603 - 1625) as a means of raising money for himself, so the Newman baronetcy was not amongst the earliest as stated here, but it was indeed alleged to have been granted in 1699."
