My dad has 388 4th cousin or closer matches, and my daughter 198. We know that about 50 of Dad's matches are from his direct paternal line.
In total Dad has over 41,000 matches and I have not bothered with any less than 20cMs unless Ancestry suggests a common ancestor or there is a large family tree. We have picked up half a dozen in the 7-8cMs range who have a common ancestor (his 5xgreat grandparents).
I like Common Ancestor feature better than the ThruLines and DNA Circles.
