In reviewing the 1932 History of the Winslow ME Church, transcribed by Debra LoSasso of our Society in 2004, I found reference on page 90 to an Hannah Cross being a member of Class #1 (meeting Sunday Mornings) and to a Thomas W. Cross and Frances Cross being members of Class #2 that met on Monday evenings dating from 1855.
An "E. Cross" was listed as a contributor in 1860.
No other mentions of Cross family members were found.
Hope this helps.
