German to English Other General / Conversation / Greetings / Letters

My question is on the connotation of this word (I know the dictionary definitions, from Duden and from DE-EN dictionaries).

In English, allegedly, supposedly, reputedly, and reportedly all convey subtle differences as to whether the speaker thinks what is being described is unsubstantiated, pure hokum, or possibly true but we just don't know.

My German text is from 1927, a physician examining Theresa Neumann, a woman who is a mystic, has visions, has "stigmata," performs miracles. He is describing her prehistory, as described by her family members. He touts himself as being objective, only interested in science, not theology. But he is also rather more inclined to think she is a "hysteric"--ie that her claims are not true.

Some examples:
Doch kann ich nicht verschweigen, daß uns brieflich von einer die Familie Neumann **angeblich** gut kennenden Seite mitgeteilt wurde, daß mancherlei psychopathische Abwegigkeiten in der weiteren und näheren Verwandtschaft vorgekommen seien.

Als ich ihr die Hand gab, zuckte sie leicht zusammen, da die Wundmale dabei **angeblich** schmerzten.

Phantastisch war sie **angeblich** nicht.

Die Geschichte der „kleinen Therese vom Kind Jesu" habe sie bald sehr lieb gewonnen, **angeblich** wegen des einfach kindlichen, bescheidenen und frommen Wesens, das der kleinen Therese eignete und das ihr immer als Ideal vorschwebte.

There are lots more. So my question is whether to give this a relatively neutral coloration (reputed to be, etc.) or a more ironic one (supposedly, etc.)

Thanks!
