Results depending if value found excel vba

Question

I have 4 columns with names list. All columns are from different excel files. I want the value from cells from column E to change in Y or N depending if the value from column D is found in other columns A,B,C:

-Y: (if D is found in A) 
-N: (if D is found in A and B) or (if D is found in C) or (if D is not found in A and B and C)

This is what i have until now :

Sub find_if_in_a_and_b()
Dim FindString As String
Dim Rng As Range
Findcell = Sheets("Sheet1").Range("D:D")
If Trim(Findcell) <> "" Then
    With Sheets("Sheet1").Range("A:B")
        Set Rng = .Find(What:=FindString, _
                        After:=.Cells(.Cells.Count), _
                        LookIn:=xlValues, _
                        LookAt:=xlWhole, _
                        SearchOrder:=xlByRows, _
                        SearchDirection:=xlNext, _
                        MatchCase:=False)
        If Not Rng Is Nothing Then
            Application.Goto Rng, True
        Else
            MsgBox "Nothing found"
        End If
    End With
End If
End Sub
Sub find_if_in_a_and_b_and_c()
Dim FindString As String
Dim Rng As Range
Findcell = Sheets("Sheet1").Range("D:D")
If Trim(Findcell) <> "" Then
    With Sheets("Sheet1").Range("A:C")
        Set Rng = .Find(What:=FindString, _
                        After:=.Cells(.Cells.Count), _
                        LookIn:=xlValues, _
                        LookAt:=xlWhole, _
                        SearchOrder:=xlByRows, _
                        SearchDirection:=xlNext, _
                        MatchCase:=False)
        If Not Rng Is Nothing Then
            Application.Goto Rng, True
        Else
            MsgBox "Nothing found"
        End If
    End With
End If
End Sub

Any help is welcomed.Thank you.

Like mates said, you dont need VBA. Make 3 auxiliary columns with "Found in A" "Found in B" "Found in C" with this formula COUNTIF(A:A;$D2) and check for Y or N. Check this image
