Sort of. Harry is not short for Harold, he was christened Harry. Harry is his middle name though, his first name is Jacob. So maybe he should be added to the list. I've used the first names that players were commonly known as during their time at Hull City, or their given first names where they were known as their nickname. So Chris Chilton rather than Christopher Chilton. I guess that could lead to 1-2 inconsistencies. Anyway - Brian Ferguson.
#4 and #3 are bit-part players from the 1910s and 1920s I think. George McLaughlin and Samuel Hamilton.
