Hey there. My brother has been researching for years and it seems that in 18XX there was a census where the Lincicum's in question were unable to read or write. As was custom in that time the census was recorded by church type folk. Since the Lincicum names seems to begin there, my brother postulated that perhaps the name we use is a typo, and that perhaps we are linthicums. Anyone that has any info please email me. I'll give my brother a call for details. He then traced the linthicum name back to Virginia/England. Which of course means that there can be a Linthicum coat of arms. If there already IS one, please email that as well. Thanks....!
