Well-wisher

Tom was so universally disliked that he didn't receive one card from a well-wisher when he was hospitalized.

I am your well-wisher.

[T]hose honest gentlemen that are always exposed to the wit and raillery of their well-wishers and companions; that are pelted by men, women, and children, friends and foes, and in a word, stand as butts in conversation, for every one to shoot at that pleases.

[T]he actual traytor or rebel is guilty of perjury in the eye of the lavv; the ſecret promoter, or vvell-vviſher of the cauſe, is ſo before the Tribunal of conſcience.

Nor did he ſeem to have made an unreaſonable reply to them both, and it vvas eaſy for a ſpeech to be received favorably amongſt vvellvviſhers.

[G]ive me the hopes of my dear girl's approaching felicity, equal to the deſires of / Her ſincereſt VVellvviſher, / LAVINIA RAWLINS.

She had still, however, her friends and well-wishers, many of whom thought, that as she was a lone woman, and known to be well to pass in the world, she would act wisely to retire from public life, and take down a sign which had no longer fascination for guests.

"You see before you," she said, with choking utterance, "one who, fallen and degraded as she is, would still venture to hope that she has a friend, at least a wellwisher, in Mr Thornton. If I am mistaken in this, alas! I am friendless."

"[…] [I]t would be a nice opportunity for any of his well-wishers to pay him a visit, if they knew how straight the path was made before them." / "I am none of his well-wishers, sir: I don't care for him."

Already a J72 0-6-0T has been promised by a well-wisher and will be re-painted in North Eastern Railway livery.
