Catherine Elizabeth English Jakeman was my great-great aunt. She came from a large family, of whom two brothers (Allan & Albert) married two sisters from another large family called Mason (Elizabeth & Alice) As far as I know, the line goes like this:
James Jakeman, an oilman from Oxford (died prior to 1849)had a son, George English Jakeman b. 18 August 1822 at Queen Street, Oxford. On 18 December 1849, he married Marrion Elizabeth Ferrie at St Pancras Old Church, New Road. They lived initially at Clarendon Rd Camberwell. George died at Tooting in 1871 aged 49. Their nine children were:
George English Jakeman b.17 Nov 1850 at Lansdown Terrace, Caledonian Rd.
Allan James English Jakeman b.22 Aug 1852 at Lavinia Grove, Caledonian: m. Elizabeth Mason 1874: d.20 Feb 1924 Forest Hill
Catherine Elizabeth English Jakeman b. 20 March 1854 Southampton St, Pentonville: m. Claudius Lawes, lived 100 Wellsley Rd: buried 8 November 1919 Queen's Rd Croydon
Jessie English Jakeman b. 17 Feb 1856 Melville Terrace, Caledonian Rd
Marrion English Jakeman b. 3 Dec 1857 Derby Rd: m.1879
Harry English Jakeman b. 4 Nov 1859 Gray's Inn Rd
Albert English Jakeman b.12 Sept 1861 Gray's Inn Rd: m.Alice Mason 27 Sept 1893, Stoke Newington. Lived 10 Dumont Rd, then 33 Bellenden Rd, Dulwich (2 children, Albert and Elsie Marion Alice, my grandmother):d.24 Sept 1933, buried Camberwell New. Occupation Dyer/Painter.
Walter English Jakeman b.October 1863 Gray's Inn Rd
Eliza English Jakeman b. 4 Nov 1866 Burleigh Rd, Kentish Town
There is some trace here of Jakemans in Dulwich, which might connect with Carol Jakeman's line?
The strange thing is, the use of the name English for the children. It wasn't used by the previous or the following generation. Some of them may have dropped the Jakeman bit altogether from what you say. BUT my grandfather's mother (Thomas William Hanner who married Elsie Jakeman), was called Marion English!! It was said that the two families (English & English Jakeman) knew each other and my grandfather and grandmother were pushed out in prams together in early life! A puzzle yet to be solved.
