Create feature class/layer with data in python list [on hold]

I want to programmatically add a layer to an MXD. The data for the layer is a list of tuples. From I what see, I need to create a feature class with this data (called invalidDataList) Below is what I have so far.

How do I do this? (This code is incoherent at the for loop)

# invalidDataList is a list of tuples, each having name,lat,lon,township,range,section
mxd_filename = r"D:\My Documents\ArcGIS\TownshipRange.mxd"
mxd_file = arcpy.mapping.MapDocument(mxd_filename)
dataframe = arcpy.mapping.ListDataFrames(mxd_file)[0]

featureClass = r"D:\My Documents\ArcGIS\invaliddata"
feature_class_name = "invaliddata"
arcpy.MakeFeatureLayer_management(feature_class, feature_class_name)

for invalidData in arcpy.da.SearchCursor((
        featureClass, 
        [NAME','LATITUDE','LONGITUDE','TOWNSHIP','RANGE','SECTION'']):
            featureClassData.append(invalidData.name,    
                                    invalidData.latitude,    
                                    invalidData.longitude,   
                                    invalidData.plssTownship,
                                    invalidData.plssRange,   
                                    invalidData.plssSection)

layer = arcpy.mapping.Layer(feature_class_name)
arcpy.mapping.AddLayer(dataframe, layer, "AUTO_ARRANGE")                    

Name: Smith Ranch latitude: 38.527444716 longitude: -107.637452472 plssTownship: 15S plssRange: 07W plssSection: 30

Name: Kinsley latitude: 39.34544716 longitude: -108.637452472 plssTownship: 5N plssRange: 01W plssSection: 3

Here is InvalidData class:

class InvalidData (object):

    def __init__(self, 
                 name = "", 
                 latitude = "",
                 longitude = "",
                 plssTownship = "",
                 plssRange = "",
                 plssSection = "",
                 ):

        self.mineName = name
        self.latitude = latitude
        self.longitude = longitude
        self.plssTownship = plssTownship
        self.plssRange = plssRange
        self.plssSection = plssSection
