The Menologium Cisterciense is said by 18th century Spanish ecclesiastical historian Enrique Flórez to have reported the following family group: Conradus, ex Sancia filia Alfonsi Magni Regis Castilliæ, genuit Luyfridum, Carolum, Conradum, Esmericum, Susannam, quæ locata est Brunoni Duci Saxoniæ, Emergardem, Adellam, Theodosinam. [Note: I assume this to be a reference to this publication: https://books.google.com/books?id=lC5SAAAAcAAJ but if so it is an erroneous citation, because Flórez says the entry is "die 7 Sept." but that day does not contain this entry, nor do I find it on adjacent days (nor, since it uses Roman/church dating, at 7 Calends Sept.), or any other day that names a Conrad or an Alfonso (as per the index).] Flórez describes this Conrad as Duke of Suevia, but the first Conrad of Swabia wasn't born until after Alfonso III died in 910 (his know children being adults at the time), while Bruno of Saxony died 30 years before Alfonso. All of it falls over a century before anyone was King of Castile. And the daughters' names seem an odd mix for this place and time. Does anyone recognize the German family being described here, or is this all just the anachronistic jumble it appears to be? taf
