Deleting rows based upon partial cell text

Dear Friends,

I have read many posts to this forum where a question like my own is posted, except those questions are based upon exact cell values/contents, but not partial contents. So .. I will ask my question below.

I would like to delete all rows (NOT the header row) where cells in column H DON'T start with the word "Name:" The cell may read "Name: John Doe" or it may read "Name: Sam Smith" or even "Betty." Of these, the row with "Betty" would be deleted, the others would remain.

Thanks for your help,
Mike
