HI Terry
I'm sorry this one has been sitting here awhile, but I know lots of people are busy or away at the moment.
Mother's milk of kind abound.
Father's law unnatural.
Brothers fight on this damned ground.
Sisters complete the cycle.
I think you fall on the last line here where cycle does not really rhyme with unnatural -- and the meter is not so smooth.
This is an interesting form (new to me) and I will return to this when I have more time to give it some thought.
Snow
Here's one I found with perfect rhymes (even the 3 syllable ones and smooth meter)
Pure promises anointed
In August's early reaping;
Celestial bliss appointed
Our oaths pledged proud for keeping.
A crazy haze September
Now fades the summer's glories;
Maydays we now remember,
Fall bonfires tell the stories.
