Timeline should support datasource like most other Kendo MVC component (eg. Grid) with additional data. eg:

        @(Html.Kendo().Timeline<Models.HistoryView>()
                  .Name("Title")
                  .DataDateField("Date")
                  .DataDescriptionField("Description")
                  .DataTitleField("Item")
                  .Orientation(TimelineOrientation.Vertical)
                  .AlternatingMode()
                  .CollapsibleEvents()
                  .DataSource(dt => dt.Read("GetHistory", "Controller").Data("getPersonID"))
        )
