Etienne Rene Bruno Gouyon Gatbeay Bruno Gouyon Gatbeay Gayneau - No sources, this is a bogus profile.

https://www.wikitree.com/wiki/Gayneau-2 Is the source of the confusion?

“ Etienne Gayneau Jr was born about 1640 in La Rochelle, Charente-Maritime, France. He was the son of Etienne Gayneau Sr and Marie Geneau. He was a stovemaker merchant when he married his wife, Lydia Mestereau, on 16 March 1653 in La Rochelle. The family migrated to Amsterdam, The Netherlands, where Marie Magdelinne was born and baptised, and later to New York. Etienne Gayneau and Lydia Mestereau arrived in New York on the ship De Bever (The Beaver) on 09 May 1661, with three of the four children who had been born in La Rochelle. Apparently, starting a new life in a new country Etienne changed the family name from Gayneau to Gano before his last two children were born in his new country. He died about 1706 in Staten Island, Richmond County, New York, British America.”

So is this bio a different person?
