Could they perhaps be Eastern Redceder? That is actually a juniper and not a true ceder, but is commonly called ceder. It is marketed as 'aromatic ceder' It is very light and straight grained with a deep reddish brown color.
From Wikipedia, about its uses:
The fine-grained, soft brittle pinkish- to brownish-red heartwood is fragrant, very light and very durable, even in contact with soil. Because of its rot resistance, the wood is used for fence posts.
