Louis McDonnell / Louis Park

I am wondering if Louis might be a McDonnell family name somewhere back along the line, or someone closely connected to the McDonnell's.

I have a Louis Desmond McDonnell birth registered in 1909, Sculcoated, he married Ellen Parker in 1933 in Sculcoates.

In 1902 Mary Ann McDonnell and John Park had a son called Louis Walter Park - who I'd guess married Louisa A Pickup in 1930 in Hull.

Perhaps it's co-incidence???? Perhaps there's more to it I'm going to discover at a later date!
