1. I believe he preferred spelling "AvRuskin" with a capital R (see for example https://humphreymiles.com/tribute/details/3735/Stanley-AvRuskin/obi... )
2. It is probably best not to enter his exact DOB here, for the privacy of his twin brother.
3. As to place of birth, a tree on MyHeritage gives Toronto while another source says Salem. Therefore I changed it just to Ontario.
