Thanks. The breeder, Mr.Tysterman, named it after his wife, so the correct name of the rose is 'Doris Tysterman'. I think in any language the correct spelling should be used. But a search of the internet shows a spelling which includes the 'h' so we have added a link for the incorrect spelling of Thysterman whch will take you straight to the rose.
I was not implying her name should be spelled incorrectly, I'm aware it is a misspelling; just that there's people that might not find the rose looking it up as it appears in several sources, like I couldn't at first. Redirecting the search here is a better idea. Didn't think of it. Thanks! :)
