SOLVED kids' fiction: orphans run away from bachelor uncle [s]

[John]

I read it back in the 70's, and recall that it was a newly printed book, though the "action" is Victorian (Edwardian?) England.
Orphaned kids (I think 3 or 4) go to live with their bachelor uncle guardian, whom they've never met. Neither side can relate to each other, although there's a scene where they're supplied with watercolors to use on Sunday afternoons as a reward for being good in church, so the uncle does make an effort. The kids run away, are caught in a storm and returned to the uncle bedraggled-as-hell, to learn he was genuinely worried about them. Happy ever after.
I believe there was a pony called Abner Abednego ... or else that was the name of the sinister jackdaw?
Been driving me crazy, so thanks in advance for your help!

This sounds like Linnets and Valerians by Elizabeth Goudge. Great book, and you should be able to find a copy pretty easily.

That was it - thanks!
