Children of Alfred + Cordelia that I am aware of are the following. Please note I did not made the research myself: * Amanda, born 1885-07-15 * Elisabeth, b. 1897-01-23 * Exilda aka Lydia, b. 1900-11-10 * Marie-Anne, b. 1900-12-10 (obviously a mistake for one of these 2, maybe tweens !) * Marie-Jeanne, b. 1902-11-10 * Blanche, b. 1909-02-25 * Delphine, b. 1911-02-03 * Cora aka Cecilia, b. 1914-09-14
Also, iIs there a mistake in Delphine's death date ? it seems she was quite young in 1928, being born in 1911 and having 3 children if I got you well.
Lastly, I understood that your uncle Roland used his mother last name; was it the same for your mother ? And did Rpland had children ?
