Day Star Series by Agnes Giberne

Published by Estes and Lauriat
1. Day Star
2. Brother Bertie
3. Warringtons Abroad
4. Little Rosy's Pet

This series is noted in an Estes and Lauriat catalogue in 1881 but I have seen no evidence that the titles were published by them. The books were published by Thomas Nelson & Sons. As regards Estes and Lauriat this appears to be a phantom series.
