Looking for help finding author of poem

[Weedon]

I know this poem was on the wall of an old house that was torn down in Virginia. Can someone tell me if they know the author or title please? Thank you.

Now read the rede of this old roof tree~.
Here be trust fast, opinion free~,
Knightly right hand and Christian knee~.
Worth in all, wit in some~,
Open laughter, slander dumb.
Hearth where rooted friendships grow
And the sparks that upward go
When the hearth flame dies below.
If thy sap in these may be~
Then fear no winter old rooftree~.

I found this. The poem appears to be related to the "Lewis Congress". Not sure what it is, I could not find any information on Wikipedia as it directed me to congressman John Robert Lewis, which is something different. It is probably stated in the book I linked above but I could not be bothered to look for it, sorry.

Anyways, your poem is found on page 9 of the book, page 23 of the pdf. However, it does not give a specific author. So I'm sorry I cannot help there. I thought maybe you didn't know about the Lewis Congress yet.
