Still digging around on ALGARs.
Had a chuckle at one discovery. Found one Arthur ALGAR part of a "transport" to Virginia in 1731 after being convicted at the Devon Assizes.
I then found another site recording the earliest ALGARs in America, amongst whom was one Arthur ALGAR who "emigrated to Virgina in 1731".
This may, or may not, be the Arthur baptised 1693 to Andrew and Mary (CURTIS) ALGAR in Yealmpton.
The ALGAR chart has been updated with a few more checked out baptisms (still mostly from the IGI as I check off the 1920s chart Richard kindly sent me a copy of, but supplemented by assorted leasing transcripts on the UK National Archives site, and web searches).
