I originally did extensive Lufkin research from 1965 to 1980 and now that I'm retired, I've renewed my Lufkin research efforts. With those efforts and that of what Kent Lufkin and Dave Lufkin have added in the last several years, this file may hold some answers for you.
I find a Warren Edward Lufkin born about 1924 who does have a brother Norman Carl Lufkin born about 1929. Warren had a son Mark. Let me know if this seems like a fit. Since this particular family's data is a bit sketchy, any other BMD details about you, your Mom or your Dad and his parent's family, that you can add will help prove the tie-in and will be very much appreciated.
If this is a match, the records tie back to Thomas Lovekin of Gloucester, Mass. 1674.
Looking forward to your reply.... Art
