No Martin Petersen Byriel is not my ancestor.
I think we now have the needed information about the Byriel ancestors given to me by the wife of a distant Byriel family member in Denmark who has done extensive research about our ancestors.
My Byriel/Mortensen ancestors immigrated from the Bevtoft and Vedsted parishes of Schleswig-Holstein.
Thank you for responding to my query. I am not a member of Ancestry.com. I just subscribed to their trial offer and decided not to continue the subscription at this time .....and tried to reply to your message earlier in the week, but the site would not accept my password since I am not a member, so I was happy to be able to reply to you this morning in this manner, so you won't spend time searching for us.
Thanks for other help you have previously given me in my searching....appreciate it very much!!
