Talk:Hariot Hamilton-Temple-Blackwood, Marchioness of Dufferin and Ava

How many children?

In the article you can read:

1) "On 23 October 1862, she married her distant cousin the 5th Baron Dufferin and Claneboye at Killyleagh Castle; they later had five daughters and seven sons." A total of twelve children!

2) "The first Marchioness of Dufferin and Ava had seven children." And then there is a list of seven children (sons and daughters).

Did she have 12 children but some died during infancy and only 7 reached adulthood or did she have 7 children at total?
