Hi Herb: We hope that you can find a direct line male with the last name of Crown to join our Crown DNA Test Group. The Y-DNA only tests for the direct male line and I know that you are descended from Susanna Crown who m. John Coale. Here is a copy of your correspondence. Maybe someone on this Crown Board can answer your question about Susanna Crown.

"Originally I thought I was descended from Joseph’s son Lancelot because you have his daughter Susanna Crown marriage to John Coale, 31 March,1798, Montgomery Co., MD. Later I found a marriage of Susanna Crown to John Coale, 11 September, 1823, Montgomery Co., MD. I sent for (and got) a certified copy of the marriage license. I know my ggg grandparents were John Coale (Cole) and Susanna Crown. Now which Susanna Crown, daughter of Lancelot b 1778 or Susan b 1797, daughter of Gerrard?
The 1850 census of Montgomery Co. has Susan (Susanna) Cole, age 49, living with her daughter and son in law, William and Sarah Case.
The 1860 census of Montgomery Co. has her, age 60, still living with her daughter and son in law.
That age on the census would make her the daughter of Gerrard, right? And too young to be the daughter of Lancelot. So I am reasonably sure I am descended from Gerrard. Now the problem, did both Susannas marry a John Coale? What was the source of your information about the marriage of Susanna and John Coale on 31 March, 1798?
Were there two John Coales, one who married the daughter of Lancelot and one who married the daughter of Gerrard?
John #2 could be the son of John #1?"
