I don't think there is a family relationship here but I'd love to be proved wrong.
My ggfather's brother Charles Clarence Edmond Pinder was born 1877 in West Hardwick which is approximately 5 miles from Warmfield.
His Father was Charles Pinder, b. before 19 March 1837 in Rugby, d. 1 Sep 1901 in Derby; his mother was Elizabeth Wilkinson b. 7 Mar 1839 in Selby, d. 25 Jul 1899 in Birmingham
I know of seven brothers and sisters, all of whom, with the exception of my ggfather have dropped off the family radar. They were Alfred William Pinder b. c1859 d. c1911 George Henry Pinder (my ggfather) b. 1862 d. 1938 Lillian Pinder b. c1865 Minnie Pinder b c1868 Clarice Helen Pinder b. c1871 d. c1872 Fanny Maude Pinder b. 1873 Leonard Pinder b. c1880 d.1971
There are huge gaps in my knowledge - e.g. I don't know of many female relatives on the Pinder line (perhaps there are none).
Any further information would be gratefully received, my brother has put a lot of work in to get what I know so far; it would be nice to be able to put something back for him.
