Hi Renee,
That question can't be answered at this time. It will probably take genetic testing to answer it. If documentation on your sons Lilly ancestors would be helpful please email me with information on your line(s) back to Robert and Mary Lilly. I will reply this weekend with what I have. robertzingo@aol.com
Sincerely, Cousin Bob
