Can you help with a poem please?

[GingleJangleScarecrow]

Trying to remember a poem from my childhood. I think it was Edward Lear or AA Milne or someone similar.

Was talking to a friend about double-barelled names and had a brief memory of a kids poem about a child with a very convoluted name......something along the lines of "Robertson-Robertson-Fortescue-Smythe", but as I don't think these were the actual names it's a bit hard to google.

Before I go through long lists of all children's ryhmes, can anybody help with the actual poem?

Is it this? users.umiacs.umd.edu/users/ridgelocal/disobedience.html

James James Morrison Morison Weatherby George Dupree!

This is probably completely wrong as my toddler sings it as a nursery rhyme but could it be "John Jacob Jingleheimer Schmidt"

@Whatchamean beat me too it. I immediately thought John Jacob Jingleheimer Schmidt as well

To not too. My phone has grammatical issues

@Barabajagal YES!!!!!! That's the one. You have saved me hours of googling. Thank you

Lima45 yes it's one of those that really gets stuck in your head

You’re welcome!

Took great care of his mother though he was only three

Is it in Now We Are Six?
I used to love reading those aloud
(My youngest is 26 but I have a tiny granddaughter now, I can start again! Thanks for reminding me, GingleJangle )

Yes, I think it must be in Now We are Six.

I have passed my copy on to my grandson and will look forward to reading it to him.

Apologies @BlueChampagne - you had it right too!

It's called "Disobedience" by A.A. Milne.

The last verse always ticked me.
The fact that J J M M W D duP had the sabre number of syllables as the whole name.
