Scott Family - related to each other?

James Scott, ESQ., born about 1800 in Omagh, Tyrone.  - married Ellen Scott,  February 28 1832 (Yesterday morning, by the Rev Wm. Mulligan, MR JAMES SCOTT, of Omagh, to ELLEN, second daughter of the late MR JOHN SCOTT, of this town [Strabane] March 3 1832 On Monday morning, in Strabane, by the Rev. William Mulligan, JAMES SCOTT, ESQ)

Both have the Scott surname but I have yet to find thier ancestors or if they are at all related. Here is the info which I have found, please feel free to tell me if anything is incorrect

James Scott, ESQ. born about 1800 in Omagh, I have no parents nor siblings. In 1864 his occupations was listed as Linen & Woollen Drapers.

Ellen Scott was born about 1805 in Strabane. She was the daughter of John Scott born about 1770 and his wife, Elizabeth (surname unknown) who was born I'm guessing about 1776? From the records I've found, it appears that John & Elizabeth also had another daughter named, Eliza Scott sister of Ellen Scott.

John Scott died in Strabane, March 9 1830 On Sunday evening last, MR JOHN SCOTT, of this town, Merchant, after a severe and protracted illness, regretted by a numerous and extensive circle of acquaintances, leaving a widow and numerous family to deplore his loss

Elizabeth died Dec 28, 1852 at Ramelton [Co Donegal]
