Hi Toni,
Further to my post on 7 March 13 on Frederick Edward Cullmer, 2nd son of Alfred and Ellen Wheeler; still nothing positive but FreeBMD has thrown up the following:
Marriages:
Frederick Edward Collimore, Eton, Q4 1889, 3a 912
Frederick Edward Colmar, Congleton [Cheshire], Q4 1898, 8a 543
Deaths:
Frederick E Collimore, aged 79, Eton, Q1 1946, 3a 1816
Frederick E Colmar, aged 86, Willesden, Q4 1958, 5f 195
Frederick E Colmar, aged 82, Epping, Q1 1963, 5a 148
There is also a Frederick Culmer, aged "[39]6", Camberwell, Q4 1902, 476. Fred was born 1867 so would have been aged around 35 in 1902 and Camberwell seems more likely than the others, I would put this possibility top of the list.
I have much more positive information on Sydney, the 3rd son:
In the 1891 census (RG12/424, f 113, p 49) Sidney is living with his uncle Henry/Harry Wheeler, his aunt Rachel and their family, as his father Alfred had died in 1888, his brother George Cullmer and his Grandmother Ellen Wheeler, are both in prison, and his mother Ellen Elizabeth Ingram has escaped arrest and fled to New Zealand.
Sydney emigrated from England to Australia, where in 1909 he married Marjorie Ann Cowie. Sydney and Marjorie had had two children; twin boys Richard Alexander Culmer and John Eugene Culmer, who were born on 8/4/1910. These events took place in Gympie, southern Queensland. However the family were in Brisbane on around 11 December 1914 as this photograph title (photograph is not of reproducible quality) published in “The Queenslander” newspaper dated 12 December 1914 informed the public:
JACK AND DICK CULMER. Four-year-old twin soldier boys who marched in the patriotic procession on St. Andrew's Day, [in Brisbane] and who collected £15/11/8d from the crowd.
The family subsequently moved to New South Wales, where Richard Alexander, having served in the RAAF in World War 2, married Annie Ellen Wilson in 1946. Sydney Culmer died in NSW in 1954 and his wife Marjorie in 1947. John died in NSW in 1979 but nothing is known of Richard. The locations in New South Wales are unknown.
