Most of the illegitimate children on this table are all legitimatio per matrimonium subsequens or legitimated by subsequent marriage. They and their descendants are excluded from the line of succession and other titles. Other monarchies are different. Monaco, for instance recognises legitimated children as eligible for the throne.
The Catholics are from the Duke of Kent's family.
The Duke's wife converted to Catholicism decades after they were married. Her later conversion did not exclude him.
Their oldest son, George Windsor, married his Catholic wife in 1988 and was thereby excluded until 2015, when the Perth Agreement was implemented. Two of his three children are Catholics. Only Lady Amelia Windsor is still in the line, but it is presumed that she will follow the lead of her siblings and parents and be confirmed [in the Catholic faith] when she is older and hence will be excluded from succession.
Their second son, Lord Nicholas Windsor, converted to Catholicism, married his wife in the Vatican, and his three children are baptised Catholics.
The Duke's brother, Prince Michael of Kent, married his Catholic wife in 1978 and was thereby excluded until 2015. His children were raised in communion with the Anglican church and have always been eligible.
^ abcIt is unclear whether baptism in the Catholic faith is sufficient to bar someone from the line of succession or whether confirmation as a Catholic is necessary. Albert and Leopold Windsor were listed on The Official Website of the British Monarchy[1] until 2015 and in the 2013 edition of Whitaker's Almanack as eligible to succeed; MSN News,[2] Debrett's and Whitaker's Almanack 2015 also list them as eligible, after Lady Amelia Windsor and before Lady Helen Taylor.
^Depending on whether Catholic minors are eligible to succeed.
^ abcdefghijklmThere are no reliable published lists of the line of succession beyond Viscount Lascelles.
