Here are the siblings of Thomas (children of Thomas Bean & Elizabeth Pitt):
ANN BEAN christened 28.6.1736 North Hayling
MARTHA BEAN christened 24.10.1742 South Hayling
SARAH BEAN christened 1743 South Hayling
RICHARD BEAN christened 3.4.1748 North Hayling
MARY ELIZABETH ANN BEAN christened 3.2.1752 North Hayling
JOSEPH BEAN christened 1754 North Hayling
JOSEPH BEAN christened 1756 South Hayling
With the last two children both being Joseph - bear in mind the fact in those days it wasn't uncommon for children to die and later offspring named after them.
There were also four other children I found with parents Thomas Bean and Elizabeth (but no mention of the mother's surname):
JOHN BEAN christened 26.9.1740 North Hayling
WILLIAM BEAN christened 8.3.1746 North Hayling
JAMES THOMAS JOHN BEAN christened 15.4.1753 North Hayling
STEPHEN BEAN christened 31.12.1757 North Hayling - died 19.1.1858
Would you like me to see if I can find any marriages for any of the above?
