Editing family members information

Hi tamim- If you wish to take more control of an IMDb page(s), in this case of family members, you will have to claim the page(s) with an active IMDbPro membership. An important note on this is that you will need an individual  IMDbPro membership for each of the name page(s) that you wish to claim. Once you have an active IMDbPro membership and the claimed page(s), you will be able to manage all other information within that page(s).  For more information on how to sign up and what's included as an IMDbPro member, I encourage you to the review the following Help Guide. In this other one, you will find How to Claim your page. In regards to the supporting evidence that we request, whether it is for a Birthdate/Death date or Birthname, we are looking for links or uploads to public records, social media links, printed publications, or official documents (driver's license, birth certificates, passports). Something important to note is that we do not accept evidence from unverifiable sources. For example, Wikipedia or any collaboratively edited wiki-style sites unless these include online citations and external links which provide supporting evidence of the subject's birth date, death date or birthname. For more detailed information on our Biographical data guidelines and on the acceptable evidence, I encourage you to review our following Help Guide.  Let us know if you have any further questions/issues! Cheers!
