sorry clover 10 , all my male line names are either donald , john , duncan , archibald , peter or 1 malcolm. what paperwork have you re James , death certificate / marriage etc.
looked on IGI on familysearch , and their are many james mclarens in or around the 1824 timeframe, within 5 years. where did he die , as the death certificate records are usually better than the birth for information. gordon
