When did Steve Harvey take Lori Harvey in as his own?

Lori, who was born in 1997, became a part of the Harvey family 

in 2007 after her mother, Marjorie Elaine, wed Steve Harvey. 

 Steve adopted all three of his wife's children, Lori, Jason, and Morgan,

 her original father's identity is unknown.

 From his two prior marriages, he has four children of his own

Wynton, Karli, Brandi, and Broderick Jr.

My parents did a wonderful job of shielding us from the media and allowing us 

 a typical upbringing so that we could just be kids and not have our every move scrutinised.
