How can I get information on Kay Lester who sang the song "Love Letters" (straight from my heart) in the 1960's?

Did this singer play in the Little House on the Prairie? Because if it is this person her name is Ketty Lester not Kay Lester. You can go on Google and type in Ketty Lester and it will give you a lot of things about her. On wikipedia it says that in 1962 she released Love Letters so if this is the right person her name is Ketty not Kay.
