About Railenda vom Comersee
Railinda of Piacenza – (c956 – c1010) [following source is not authoritative]
Italian mediaeval princess
Railinda was the daughter of Riprando (Wiprando) (c927 – 999), Count of Piacenza and Como, himself the son of Count Olderado of Como and his wife Railinda of Verticilio. Railinda was married (c971) to Oberto II d’Este (c945 – c1014), Margrave of Tuscany, whom she predeceased. Her daughter, Bertha of Tuscany (c990 – 1037) became the wife of Odalrico Manfredo II, Margrave of Susa and Turin, and left issue. Railinda was the maternal grandmother of the famous heiress, Adelaide of Turin, and through her she was ancestress of the counts and dukes of Savoy, and the kings of Sardinia and Italy.
Although there is a persistent tradition to the effect that she survived Count Sigfred and took Oberto II degli Obertenghi as her second husband, there is no primary nor reliable secondary source for this information.
