You are correct.Croom is a descriptive place name not a family name that the town was named after.I looked cromadh up in a gaelic dictionary awhile ago and the meaning is roughly crooked, bend, bent...etc.Croom in Limerick is on a river, a mill-Croom Mill-is there, I bet the village is on a crook in the river.The rumored castle Croom does exist.It is in ruins.The castle belonged to the Fitzgeralds and was destroyed in a Geraldine war. An aside note there is also a Macroom Ireland.
I would like to know where people have heard that their families came from Ireland.Is this family lore?Did they pick it up from the internet?Did they find Croom, Limerick, co on an atlas and make a connection? Where did the name Joel come from?I have seen a citation for a Joel Croom, but in VA.I'll try and find it.
If you look in a high quality atlas you will find several towns named croom in gaelic and english areas of the world.
I've look at many passenger list and have found no Irish Croom's.I have found Scottish and English Croom's (In England: Cornwall, Devon, Dorset, Hampshire, Somerset).
I have seen a John (Courve) Croom on a passenger list from Somerset, England. He was a Monmouth rebellion prisoner sentence to the New World.His transport date was 1685.He was probably sent to Barbados or possibly VA. I haveread 1663 abt birthdate as well as 1683 for Daniel Croom.If the 1683abt date is true John could be his father-ok this is major speculation. Any comments?
