There are several errors in this write-up; First, Alicia Crossland was the daughter of John Crossland and Alicia Hawksworth. She had no brothers, thus as the oldest, her father's heir allowing her grandson Cecil to quarter the Crossland and Calvert arms. After her death, Leonard Calvert married Grace Crossland, the daughter of Thomas Crossland and Joanna, presumably Hawksworth. Currently, there are only 2 proven children of Leonard and Alice, Sir George, Christopher and Dorothy. at this time, no others have be substantively proven
Their son George was the only one knighted and therefore called Sir, Leonard was not, nor was the remaining Lords Baltimore.
Joanne Calvert
