Declare a variable of type cardHolderInfo in your Charge class:

Public <g class="gr_ gr_84 gr-alert gr_spell gr_inline_cards gr_run_anim ContextualSpelling ins-del multiReplace" id="84" data-gr-id="84">TheCardHolder</g> as cardHolderInfo

You could also use a property:

Private <g class="gr_ gr_216 gr-alert gr_spell gr_inline_cards gr_run_anim ContextualSpelling ins-del multiReplace" id="216" data-gr-id="216">aCardHolder</g> as cardHolderInfo

Public Property <g class="gr_ gr_310 gr-alert gr_spell gr_inline_cards gr_run_anim ContextualSpelling ins-del multiReplace" id="310" data-gr-id="310">TheCardHolder</g> as cardHolderinfo

Get

   return aCardHolder

End gGet

Set(Value as cardHolderInfo)

aCardHolder = value

End Set

Do you know about auto properties in VB.NET? It can save you from not using the private backing variable for a public property.
