I have a very beautiful picture of my grand-mother taken by Lékégian in 1897. I know the exact date because she gave it to her aunts in Cairo with her signature and date. She was born in Cairo on September 4th, 1877. I think Lékégian was working untill ten years later but I have to check, it is very easy for me. Anyway, in the Egyptian Directory "L'indicateur Egyptien" de Stefano G. Poffandi Printed in Alexandria in December 1900 he is still mentioned as follows (Page 159 Cairo inhabitants)
Lekegian G. and Cie, photographes, 7 sharia Kamel, Esbekieh.
