Hi
From the Oxfordshire Family History Society CD of transcribed parish records of St John The Evangalist Church Taynton the following can be seen:
The name is recorded as TAPLEN, TAPLIN, TAPLYN, TAPLINE,TAPLING, TAPPLYNE
The first baptism is
1566 May (Sunday) 19 BYRCHALL Thomas alias Taplen son of Thomas the Elder
The first marriage is
1579 26 Nov BYRCHALL alias Taplin Thomas otp
WEMAN Ales (?) of DUSBURABAT in the diocese of Gloucester
The first burial is
1570 10 July BYRCHALL alis Taplyn
Mayry wife of Thomas the Elder
Interesting and curious that the family repeatedly used two last names
Hope this helps
