My great-great grandfather, Ernest Gilbert Croshaw (born October 2nd, 1886), served in the Royal Naval Air Service; his service numbers were 231819 and F31819. Is there any way I can find a photograph of him, as there are none in my family's albums?
Also, for my other great-great grandfather, Charles Victor Jackson (born in 1911 in Leeds); I think he was a seaman, but I can't find photographs of him either.
Anything would be useful, thank you!☺️
