Seems good to me, Sirilia may have only once visited Hazel's blacksmith and most likely doesn't remember Hazel without a picture or looking at her (due to her temporary retiring).
Considering that Hazel does mining (presumably on the Rock Tunnel) and Sirilia's manor is North-West of Lavender Town, perhaps Sirilia has seen Hazel mining with her Sableye.
