Robert Fitzhamo(Fitzhamon),Earl of Gloucester,who died young and in the King's service was also called the Lord of Tewkesbury. His family served,Duke William in Normandy and likely came with his entourage.His father Haimo and Grandfather Richard were hereditary feudal lords in Lower Normandy. Apparently they earned the respect of the native Saxons as well as their Norman peers.
Maureen Ash's characters had depth, vibrancy and very much came alive to tell their own story. I hope there will be a sequel as Fitzhaimo's relationship with Sybil de Montgomery has just begun with the ending of the book. The remainder of their life appears to be eventful and worthwhile to read about in such eventful times.
Their daughter Mabel married an illegitimate son of Henry I and together they established a line of important personages in England.
I hope to hear about them soon.
