What is the proper way to greet a Noble Earls?

The Right Honourable (abbreviated as The Rt Hon., The Rt Hon or The Rt. Hon.) is an honorific prefix that is traditionally applied to certain people in the United Kingdom, Canada, Australia, New Zealand, the Anglophone Caribbean and other Commonwealth Realms, and occasionally elsewhere. Examples of this are 'The Right Honourable David Cameron MP' (Prime Minister of the United Kingdom), 'The Right Honourable Stephen Harper PC MP' (Prime Minister of Canada) and 'The Right Honourable John Key MP' (Prime Minister of New Zealand).

The proper way to address an Earl is "Your Lordship." His wife is a Countess, addressed as "Your Ladyship" regardless of her nationality. Her children from a previous marriage do not receive titles. Children born within the marriage are Lady if a daughter and The Honourable if sons. The eldest son, however, is styled as Lord.

An Earl is formally announced as "The Right Honourable Earl of London", and his wife as "The Right Honourable Countess of London" regardless of her nationality.

In conversation they are Lord & Lady London, and are addressed as My Lord or My Lady.

Children from previous marriages are not given courtesy titles, only children born in legitimate wedlock are titled and are in line for the Earldom when the Earl dies.

Stepchildren receive no titles, though they would if the Earl adopted them. The wife's nationality is irrelevant. She is a countess like any other woman who marries an earl.

See the site below on forms of address:

You address them as My Lord and My Lady.

Or Sir and Ma'am, after invited to do so.

The American birth of the wife is irrelevant.

The children of previous marriages wouldn't have titles.

The proper form for an Earl and Countess:

a) if non-Royal (such as The Earl of Leicester): My Lord and My Lady upon introduction, Sir and Ma'am thereafter.

b) if a Royal (such as the Earl of Wessex): Your Royal Highness first, Sir and Ma'am thereafter.

A wife takes the Mrs. form of her husband's title. Thus, the Earl of Leicester is known as The Countess of Leicester.

Sup?

Wow, thanks! I was asking myself the same thing yesterday
