I have traced my Duncan ancestors in Scotland almost entirely through the internet. My brick walls are the exact immigration date, and ships name for my G-G Grandfather's passage to America but I am pretty clear on who came with him and the latest date he could have come.Most of all I am stuck unable to find anything at all about my G-G-G-G-Grandfather. I have found lots on my G-G-G-Grandfather, dates of birth for all his children, his marriage and his own birth information, but nothing on his father or mother, not even a name. His father would have been born around the time that the clans were suffering the aftermath of Culledon. I have fallen back on searching by using the customs in naming children and searching for him or his wife based on how his son named his children. The family has been consistantly in Alyth from at least 1774. I wonder if maybe they were from elsewhere prior to 1774 and were motivated to move to the Alyth area because of the impact of Culledon. I am also wondering if that event might have in some way been cause for names to not be recorded or records well kept. I wondered if the effects of Culledon were still having any impact on this sort of thing 25 years later as well.
