Hello: Thank you. In the realm of the Markham surname, it happened that the name of Daniel Markham became a confused issue, very confused, mixed, and about as bad as it can be. The article is not complete, but the bulk of it has been put out, for others to know about. Printed book knowledge gets repeated and even distorted over time, but when one is able to get back to primary record, and understand somewhat, what one is looking at, absorb that over time, things are different, and one needs to be 'incredibly specific' in problematic areas. The essay is not finished, but will be further corrected, better worded where I can, etc. Tom.
