How many siblings does Mary Mary have?

Mary Cassatt had 6 other siblings, but two died in infancy. So, for the majority of her life she only had 4 sibblings.

There is nothing in the Bible to prove if she had siblings. There are references to a sister or sisters but this reference could also mean cousins. She may have had a half sister also but there is no...

Three half-siblings: Elizabeth I, Edward VI and Henry Fitzroy. Possibly, her father had more illigitimate children with Mary Boleyn, but they might be her husband's as well.

She had two younger siblings, Jack and Lottie Pickford, who also became actors.

If by Mary you mean the virgin Mary then she has only one child which is jesus christ
