Roger de Montgomery
Roger III de Poitevin, de Montgomery, was the third son of Roger II de Montgomery, Earl of Shropshire and Shrewsbury, who died in 1094 CE.
In 1102 Roger III joined Robert II Curthose, in a failed rebelled against Henry I King of England, who was the father of Robert II Curthose.
Due to the failed uprising, Roger III and his brothers lost most of their properties in England. Roger III retreated to his property in La Marche, France. After 1109 CE, Roger appears to have lost interest in governing La Marche, his wife and son governed the region.
What is interesting is his given arms, suggesting a predecessor of the, "Knights of the Cross with the Red Star". This order was officially founded in 1233 CE, more then 100 years after Roger's death.
