Ron: Have some data regarding Lincicum/Lincicome. First of all I have you as son of Cecil,son of Edmund,Son of Jesse, son of Caleb. Caleb was my gg-grandfather. My data shows the name switch from LINCICOME to LINCICUM occurring with Caleb ...first child of Nathan LINCICOME.
Im sure the LINTHICUMs are related but maybe not in this country ...there were LINCICUMs in Wales an the late 1500s ...
Would be happy to exchange data etc ...if you are interested e-mail is:
firstname.lastname@example.org ...(the first letter is a lower-case L)
