One of my ancestors Phillippa Symons Metherell eventually turned up transcribed as 'Symons Philips' (admittedly this was 1891 not 1911)
While waiting for the original scan to download, I was preparing to write a scathing letter to Ancestry . . . then, guess what . . . that was exactly how it was written by the enumerator! All the other entries for the household were written with the surname last, so clearly a misunderstanding by someone back in 1891 . . . and full marks to the transcriber!
I get as frustrated as anyone by obviously lazy transcription work, but I agree, write what you see. It could take an awful lot of time and a lot of intuition to try to 'correct' them all.
